# Auto-Facing Feature Documentation
|
||||
|
||||
## Overview
|
||||
|
||||
The `auto_facing` parameter ensures the camera automatically points directly at the target subject from any horizontal angle position. This feature is now available in both **Object Focus Camera v7** and **Cinematography Prompt Builder**.
|
||||
|
||||
---
|
||||
|
||||
## Purpose
|
||||
|
||||
When positioning the camera at angles (left, right, side, back), `auto_facing` controls whether the camera:
|
||||
- ✅ **Points directly at the subject** (auto_facing = True)
|
||||
- ❌ **Maintains forward orientation** without explicitly facing the subject (auto_facing = False)
|
||||
|
||||
---
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### Parameter Specification
|
||||
|
||||
```python
|
||||
"auto_facing": ("BOOLEAN", {
|
||||
"default": True,
|
||||
"tooltip": "Automatically face camera toward target subject (recommended for object photography).\n"
|
||||
"• True = Camera points directly at subject from chosen angle\n"
|
||||
"• False = Camera positioned at angle but may not face subject directly"
|
||||
})
|
||||
```
|
||||
|
||||
### Prompt Positioning Strategy
|
||||
|
||||
**Key Finding**: Based on user experience with vision-language models, placing `auto_facing` guidance **at the beginning of the prompt** provides maximum attention weight and effectiveness.
|
||||
|
||||
**Prompt Structure:**
|
||||
|
||||
```
|
||||
[FACING DIRECTIVE] + [Main Camera Prompt] + [Details]
|
||||
```
|
||||
|
||||
**Examples:**
|
||||
|
||||
#### Simple Prompt (English):
|
||||
```
|
||||
Facing the dishwasher directly, An eye-level medium shot of the dishwasher, taken from a vantage point two meters away, positioned from thirty degrees to the left for a corner perspective, with deep depth of field keeping everything in focus, in architectural style
|
||||
```
|
||||
|
||||
#### Professional Prompt (Chinese):
|
||||
```
|
||||
面对dishwasher，Next Scene: 将镜头转为标准镜头(50mm)，中景构图，平视查看dishwasher，从左侧30度拍摄,呈现转角视角，距离两米
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## When Auto-Facing Is Applied
|
||||
|
||||
### ✅ Active Conditions:
|
||||
- `auto_facing = True` (default)
|
||||
- `horizontal_angle != "Front View (0°)"` (since front view already implies facing)
|
||||
|
||||
### ❌ Not Applied When:
|
||||
- `auto_facing = False`
|
||||
- `horizontal_angle = "Front View (0°)"` (redundant - front view inherently faces subject)
|
||||
|
||||
---
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Example 1: Dishwasher Side View with Auto-Facing
|
||||
|
||||
**Settings:**
|
||||
- Target Subject: `dishwasher`
|
||||
- Shot Type: `Medium Shot (MS)`
|
||||
- Camera Angle: `Eye Level`
|
||||
- Horizontal Angle: `Side Left (90°)`
|
||||
- **auto_facing: `True`** ✅
|
||||
|
||||
**Result:**
|
||||
Camera positions at the left side (90°) AND rotates to face the dishwasher directly, ensuring the dishwasher is centered in frame despite the side positioning.
|
||||
|
||||
---
|
||||
|
||||
### Example 2: Architectural Context Shot without Auto-Facing
|
||||
|
||||
**Settings:**
|
||||
- Target Subject: `kitchen counter`
|
||||
- Shot Type: `Wide Shot (WS)`
|
||||
- Camera Angle: `Eye Level`
|
||||
- Horizontal Angle: `Angled Right 30°`
|
||||
- **auto_facing: `False`** ❌
|
||||
|
||||
**Result:**
|
||||
Camera positions at 30° to the right but maintains forward orientation, potentially showing the counter as part of a broader environmental context rather than centered.
|
||||
|
||||

|
||||
|
||||
## Technical Implementation
|
||||
|
||||
### Cinematography Prompt Builder
|
||||
|
||||
#### Simple Prompt Generation ([cinematography_prompt_builder.py:685-688](nodes/camera/cinematography_prompt_builder.py#L685-L688)):
|
||||
|
||||
```python
|
||||
# AUTO-FACING: Add at the VERY BEGINNING for maximum attention weight
|
||||
# Only add if enabled AND not front view (front view already implies facing)
|
||||
if auto_facing and horizontal_angle != "Front View (0°)":
|
||||
parts.append(f"Facing {subject} directly")
|
||||
```
|
||||
|
||||
#### Professional Prompt Generation ([cinematography_prompt_builder.py:757-763](nodes/camera/cinematography_prompt_builder.py#L757-L763)):
|
||||
|
||||
```python
|
||||
# AUTO-FACING: Add at BEGINNING for maximum attention (before "Next Scene:")
|
||||
# Only add if enabled AND not front view
|
||||
if auto_facing and horizontal_angle != "Front View (0°)":
|
||||
if language in ["Chinese (Best for dx8152 LoRAs)", "Hybrid (Chinese + English)"]:
|
||||
prompt_parts.append(f"面对{subject}") # "Facing {subject}"
|
||||
else:
|
||||
prompt_parts.append(f"Facing {subject} directly")
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Why Positioning Matters
|
||||
|
||||
### User Observation:
|
||||
> "i know it is important if you merg it to prompt at begiing it will have more affect base on my experince"
|
||||
|
||||
This aligns with attention mechanisms in transformer-based vision-language models:
|
||||
|
||||
1. **Positional Bias**: Tokens at the beginning of prompts receive higher attention weights
|
||||
2. **Semantic Anchoring**: Early instructions establish the primary directive for the generation
|
||||
3. **Context Precedence**: Models process sequential information with recency and primacy effects
|
||||
|
||||
By placing `auto_facing` directive **first**, we ensure maximum model attention to this critical orientation instruction.
|
||||
|
||||
---
|
||||
|
||||
## Integration with Other Features
|
||||
|
||||
### Compatible with:
|
||||
- ✅ All horizontal angles (15°, 30°, 45°, 90°, 180°)
|
||||
- ✅ All vertical camera angles (Eye Level, High Angle, Low Angle, etc.)
|
||||
- ✅ All shot sizes (ECU to EWS)
|
||||
- ✅ Perspective correction modes (Natural, Architectural, Tilt-Shift)
|
||||
- ✅ All lens types
|
||||
- ✅ Chinese/English/Hybrid language modes
|
||||
|
||||
### Automatically Disabled:
|
||||
- Front View (0°) - redundant since front view inherently faces subject
|
||||
- When explicitly disabled by user (`auto_facing = False`)
|
||||
|
||||
---
|
||||
|
||||
## Practical Use Cases
|
||||
|
||||
### 🎯 Object Photography (Recommended: True)
|
||||
- Product photography requiring subject prominence
|
||||
- Furniture visualization from multiple angles
|
||||
- Appliance close-ups (dishwashers, ovens, refrigerators)
|
||||
- Detail shots of architectural elements
|
||||
|
||||
### 🏛️ Environmental Photography (Consider: False)
|
||||
- Architectural context shots
|
||||
- Room overview with subject as part of environment
|
||||
- Documentary-style environmental capture
|
||||
- Spatial relationship emphasis over subject focus
|
||||
|
||||

|
||||
|
||||
---
|
||||
|
||||
## Key Improvements
|
||||
|
||||
### 1. Auto-Facing Placement
|
||||
**Before:** Not available in Cinematography Prompt Builder
|
||||
**After:** Added at the BEGINNING of prompts for maximum attention weight
|
||||
|
||||
**User Insight:** "i know it is important if you merg it to prompt at begiing it will have more affect base on my experince"
|
||||
|
||||
This placement leverages positional bias in vision-language models.
|
||||
|
||||
---
|
||||
|
||||
### 2. Distance Chinese Precision
|
||||
|
||||
**Before:**
|
||||
```
|
||||
距离远距离 (distance far distance) ❌ Generic, redundant
|
||||
距离中等距离 (distance medium distance) ❌ Vague
|
||||
```
|
||||
|
||||
**After:**
|
||||
```
|
||||
距离四米 (distance 4 meters) ✅ Specific
|
||||
距离两米半 (distance 2.5 meters) ✅ Precise with half meters
|
||||
距离零点八米 (distance 0.8 meters) ✅ Handles decimals
|
||||
```
|
||||
|
||||
**Chinese Number Mapping:**
|
||||
- Whole numbers: 一米, 两米, 三米, 四米, etc.
|
||||
- Half meters: 半米, 一米半, 两米半, etc.
|
||||
- Decimals: 零点八米, 两点五米, etc.
|
||||
|
||||
---
|
||||
|
||||
### 3. English Mode Bug Fix
|
||||
|
||||
**Issue:** Professional English prompts were bypassing the auto_facing logic
|
||||
|
||||
**Before:**
|
||||
```
|
||||
Next Scene: Change to Normal (50mm), MS framing... ❌ Missing "Facing" clause
|
||||
```
|
||||
|
||||
**After:**
|
||||
```
|
||||
Facing the refrigerator directly, Next Scene:, Change to Normal (50mm), MS framing... ✅
|
||||
```
|
||||
|
||||
**Fix:** Updated English mode code path to include `prompt_parts` with auto_facing directive
|
||||
|
||||
---
|
||||
|
||||
## Auto-Facing Logic
|
||||
|
||||
### When Active:
|
||||
- ✅ `auto_facing = True` (default)
|
||||
- ✅ `horizontal_angle != "Front View (0°)"`
|
||||
|
||||
### When Inactive:
|
||||
- ❌ `auto_facing = False` (user disabled)
|
||||
- ❌ `horizontal_angle = "Front View (0°)"` (redundant - front view already faces subject)
|
||||
|
||||
---
|
||||
|
||||
## Language Support
|
||||
|
||||
### Chinese Mode:
|
||||
```
|
||||
面对{subject} Next Scene: ...
|
||||
```
|
||||
|
||||
### English Mode:
|
||||
```
|
||||
Facing {subject} directly, [prompt]...
|
||||
```
|
||||
|
||||
### Hybrid Mode:
|
||||
```
|
||||
面对{subject} Next Scene: ... (Chinese cinematography + English details)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Integration Status
|
||||
|
||||
✅ **Cinematography Prompt Builder** - Fully integrated
|
||||
✅ **Object Focus Camera v7** - Already had auto_facing
|
||||
✅ **Simple Prompt Generation** - Working
|
||||
✅ **Professional Prompt Generation** - Working (bug fixed)
|
||||
✅ **All Language Modes** - Working (Chinese/English/Hybrid)
|
||||
|
||||

||||
1. **cinematography_prompt_builder.py**
|
||||
- Added `auto_facing` parameter (lines 159-165)
|
||||

|
||||
- Fixed `_generate_simple_prompt()` with early auto_facing placement
|
||||
- Fixed `_generate_professional_prompt()` with early auto_facing placement
|
||||

|
||||
|
||||
## User Confirmation
|
||||
|
||||
User prompt example:
|
||||
```
|
||||
Next Scene: 将镜头转为标准镜头(50mm)，全景构图，平视查看the refrigerator ，距离远距离
|
||||
```
|
||||
|
||||
**Issues identified and fixed:**
|
||||
1. ❌ No auto_facing clause → ✅ "面对" added when using angled views
|
||||
2. ❌ "距离远距离" (distance far distance) → ✅ "距离四米" (distance 4 meters)
|
||||
3. ❌ Mixed language "the refrigerator" → Still present but acceptable for Hybrid mode
|
||||
|
||||
**Recommendations for user:**
|
||||
- Use Chinese subject name "冰箱" OR keep "the refrigerator" (both work)
|
||||
- Select angled horizontal angles (15°, 30°, 45°, 90°) to activate auto_facing
|
||||
- Default `auto_facing = True` ensures camera points at subject
|
||||

|
||||
|
||||
### Added - Cinematography Prompt Builder Enhancements ⭐
|
||||
|
||||
#### New Parameters for Professional Architectural Photography
|
||||
|
||||
- **Horizontal Angle Control** - Camera position around object:
|
||||
- 10 position options: Front (0°), Angled Left/Right (15°, 30°, 45°), Side (90°), Back (180°)
|
||||
- Natural language descriptions: "from thirty degrees to the left for a corner perspective"
|
||||
- Full Chinese translation support for all angles
|
||||
- Enables precise 3D camera positioning combined with existing vertical angles
|
||||
|
||||
- **Perspective Correction System** - Keep vertical lines straight:
|
||||
- **Natural (Standard Lens)** - Default mode with natural perspective convergence
|
||||
- **Architectural (Keep Verticals Straight)** - Professional architectural photography mode
|
||||
- **Tilt-Shift (Full Perspective Control)** - Advanced mode with selective focus plane
|
||||
- Automatic tilt-shift lens selection when Full Perspective Control enabled
|
||||
- System prompt guidance for maintaining parallel vertical lines
|
||||
- Validation warnings for incompatible camera angle combinations
|
||||
|
||||
#### Enhanced Prompt Generation
|
||||
|
||||
- **Simple Prompt Updates**:
|
||||
- Horizontal angle positioning integrated into natural language flow
|
||||
- Perspective correction guidance added for architectural mode
|
||||
- Example: "positioned from thirty degrees to the left for a corner perspective, with careful framing to keep all vertical lines parallel"
|
||||
|
||||
- **Professional Prompt Updates**:
|
||||
- Chinese translations for horizontal angles (从左侧30度拍摄,呈现转角视角)
|
||||
- Chinese translations for perspective correction (保持所有垂直线平行,防止透视畸变)
|
||||
- Integrated into dx8152 LoRA-optimized prompt structure
|
||||
|
||||
- **System Prompt Enhancements**:
|
||||
- Architectural guidance automatically appended when perspective correction enabled
|
||||
- "IMPORTANT: Maintain parallel vertical lines in architectural photography. Keep the camera level..."
|
||||
- Applied to all 3 system prompt modes (Professional, Research-Validated, Simple/Beginner)
|
||||
|
||||
#### New Helper Methods
|
||||
|
||||
- `_get_horizontal_angle_description()` - Converts angle selections to natural language (English + Chinese)
|
||||
- `_get_perspective_correction_prompting()` - Generates perspective guidance text (English + Chinese)
|
||||
|
||||
#### Enhanced Validation
|
||||
|
||||
- **Perspective Correction Compatibility Check**:
|
||||
- Warns if perspective correction enabled with non-level camera angles
|
||||
- "⚠️ Perspective correction requires eye-level camera angle. Vertical lines will converge with tilted camera positions."
|
||||
- Prevents common architectural photography mistakes
|
||||
|
||||
### Changed
|
||||
|
||||
- **Cinematography Prompt Builder**:
|
||||
- Function signature updated with `horizontal_angle` and `perspective_correction` parameters
|
||||
- Lens auto-selection logic enhanced for tilt-shift mode

|
||||
- Aligns with vision-language research showing distance-based positioning more reliable than degree-based
|
||||
- Perspective correction uses explicit natural language guidance for architectural straight verticals
|
||||
|
||||
- **Backwards Compatibility**:
|
||||
- All new parameters have sensible defaults (Front View, Natural perspective)
|
||||
- Existing workflows continue working without modification
|
||||
- Progressive enhancement approach for advanced users
|
||||
|
||||

# Cinematography Prompt Builder - Complete Implementation Summary
|
||||
|
||||
## Overview
|
||||
|
||||
Complete implementation of the Cinematography Prompt Builder node based on **Nanobanan's 5-ingredient camera prompting formula**, incorporating research-validated best practices and working examples.
|
||||
|
||||
**Implementation Date:** 2025-01-06
|
||||
**Version:** v2.4.0 (pending release)
|
||||
**Author:** Amir Ferdos (ArchAi3d)
|
||||
|
||||
---
|
||||
|
||||
## What Was Implemented
|
||||
|
||||
### ✅ 1. System Prompt Addition
|
||||
**File:** [nodes/camera/cinematography_prompt_builder.py](nodes/camera/cinematography_prompt_builder.py)
|
||||
**Documentation:** [SYSTEM_PROMPT_UPDATE.md](SYSTEM_PROMPT_UPDATE.md)
|
||||
|
||||
**Changes:**
|
||||
- Updated `RETURN_TYPES` from 3 to 4 outputs (added `system_prompt`)
|
||||
- Added `_get_cinematography_system_prompt()` method with **3 intelligent variants**:
|
||||
- **Simple/Beginner Mode** (default): Focuses on Nanobanan's 5 ingredients
|
||||
- **Professional Mode** (Chinese + presets): dx8152 LoRA optimization, Chinese terms
|
||||
- **Research-Validated Mode** (`show_advanced_info=True`): M-RoPE, guidance scale 6-8, dual-pathway architecture
|
||||
- System prompt automatically adapts to user's configuration
|
||||
|
||||
**Impact:** Node now matches output pattern of all other camera nodes (Object Focus Camera v7/v6/v5, Scene Photographer) with `(prompt, system_prompt, description)` structure.
|
||||
|
||||
---
|
||||
|
||||
### ✅ 2. Prompt Format Fixes
|
||||
**File:** [nodes/camera/cinematography_prompt_builder.py](nodes/camera/cinematography_prompt_builder.py)
|
||||
**Documentation:** [PROMPT_FORMAT_FIXES.md](PROMPT_FORMAT_FIXES.md)
|
||||
|
||||
**3 Critical Bugs Fixed:**
|
||||
|
||||
#### Bug 1: Using Abbreviations Instead of Full Shot Names
|
||||
**Before:** `A shoulder level ecu of stove oven...`
|
||||
**After:** `An eye-level extreme close-up of stove oven...`
|
||||
**Fix:** Added `get_shot_full_name()` method returning spelled-out shot types
|
||||
|
||||
#### Bug 2: Vague Distance Descriptions
|
||||
**Before:** `...taken from very close distance...`
|
||||
**After:** `...taken from a vantage point thirty centimeters away...`
|
||||
**Fix:** Always use specific distance in natural language (centimeters for <1m, meters for ≥1m)
|
||||
|
||||
#### Bug 3: Incorrect Angle Names
|
||||
**Before:** `A shoulder level...` (doesn't exist in cinematography)
|
||||
**After:** `An eye-level...`
|
||||
**Fix:** Proper angle cleaning preserves standard cinematography terms
|
||||
|
||||
**Result:** Prompts now match working example format exactly with natural language, spelled-out shot types, and specific distances.
|
||||

## Key Technical Implementation Details
|
||||
|
||||
### System Prompt Logic (Lines 390-441)
|
||||
|
||||
```python
|
||||
def _get_cinematography_system_prompt(self, prompt_language, show_advanced_info,
|
||||
material_preset, quality_preset):
|
||||
"""Generate dynamic system prompt based on configuration."""
|
||||
|
||||
# PROFESSIONAL MODE: Chinese + dx8152 LoRA optimization + presets
|
||||
if (prompt_language in ["Chinese (Best for dx8152 LoRAs)", "Hybrid (Chinese + English)"]
|
||||
and (material_preset != "None (Manual entry)" or quality_preset != "None (Manual entry)")):
|
||||
return "You are a professional cinematographer specializing in Qwen-VL camera control..."
|
||||
|
||||
# RESEARCH-VALIDATED MODE: Advanced technical mode with PDF findings
|
||||
elif show_advanced_info:
|
||||
return "You are an expert cinematographer trained in vision-language spatial reasoning..."
|
||||
|
||||
# SIMPLE/BEGINNER MODE: Nanobanan's 5-ingredient framework (default)
|
||||
else:
|
||||
return "You are a professional photographer following the five-ingredient framework..."
|
||||
```
|
||||
|
||||
### Full Shot Name Logic (Lines 369-381)
|
||||
|
||||
```python
|
||||
def get_shot_full_name(self, shot_type):
|
||||
"""Extract full natural language name from shot type (not abbreviation)"""
|
||||
full_names = {
|
||||
"Extreme Close-Up (ECU)": "extreme close-up",
|
||||
"Close-Up (CU)": "close-up",
|
||||
"Medium Close-Up (MCU)": "medium close-up",
|
||||
"Medium Shot (MS)": "medium shot",
|
||||
"Medium Long Shot (MLS)": "medium long shot",
|
||||
"Full Shot (FS)": "full shot",
|
||||
"Wide Shot (WS)": "wide shot",
|
||||
"Extreme Wide Shot (EWS)": "extreme wide shot"
|
||||
}
|
||||
return full_names.get(shot_type, shot_type.lower().split("(")[0].strip())
|
||||
```
|
||||
|
||||
### Distance Formatting Logic (Lines 474-479)
|
||||
|
||||
```python
|
||||
# Distance: "taken from a vantage point [distance] meters away" (ALWAYS specific)
|
||||
# For distances under 1 meter, use "centimeters" for better readability
|
||||
if distance < 1.0:
|
||||
cm_distance = int(distance * 100)
|
||||
cm_words = self._int_to_words(cm_distance)
|
||||
parts.append(f"taken from a vantage point {cm_words} centimeters away")
|
||||
else:
|
||||
parts.append(f"taken from a vantage point {distance_words} meters away")
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Research Integration
|
||||
|
||||
All implementations incorporate findings from **"Camera View Control in Vision-Language Image Editing Models"** research paper:
|
||||
|
||||
1. **Five-Ingredient Framework** (Page 5): Subject, shot type, angle, focus/DOF, style
|
||||
2. **Distance-Based Positioning** (Page 5): "10m to the left" > "45 degrees counterclockwise"
|
||||
3. **M-RoPE Position Embeddings** (Page 1-2): 3D spatial understanding
|
||||
4. **Dual-Encoding Pathways** (Page 2-3): Semantic (identity) + Reconstructive (appearance)
|
||||
5. **Guidance Scale 6-8** (Page 4): Optimal for camera control workflows
|
||||
6. **Natural Language Paradigm** (Page 5): No pixel coordinates, spatial language
|
||||

# Cinematography Prompt Builder - Test Cases
|
||||
|
||||
## Overview
|
||||
|
||||
This document shows how the new Cinematography Prompt Builder node can reproduce the 7 working examples from Nanobanan's proven formula.
|
||||
|
||||
## Node Design Philosophy
|
||||
|
||||
**4-Layer System:**
|
||||
- **Layer 1 (Required)**: Nanobanan's 5 Ingredients - Simple & Effective
|
||||
- **Layer 2 (Optional)**: Professional cinematography enhancements
|
||||
- **Layer 3 (Optional)**: Material details (37 presets)
|
||||
- **Layer 4 (Optional)**: Quality presets (15 presets)
|
||||
|
||||
**Nanobanan's 5 Ingredients:**
|
||||
1. Subject - What to photograph ("the watch", "the stove")
|
||||
2. Shot Type - How to frame it ("close-up", "wide shot")
|
||||
3. Angle - Where camera is ("eye level", "low angle")
|
||||
4. Focus/DOF - What's sharp/blurred ("shallow depth of field")
|
||||
5. Style/Mood - Overall vibe ("cinematic", "clean")

|
||||
---
|
||||
|
||||
## Key Features Demonstrated
|
||||
|
||||
### 1. Auto-Calculations
|
||||
- **Shot Size → Distance**: Full Shot = 4.5m, Close-Up = 0.8m, etc.
|
||||
- **Shot Size → Lens**: Close-Up = Portrait 85mm, Wide Shot = Wide Angle 24-35mm
|
||||
- **Shot Size → DOF**: Wide Shot = Deep, Close-Up = Shallow
|
||||
|
||||
### 2. Number-to-Words Conversion
|
||||
- `4.5` → "four and a half"
|
||||
- `2.5` → "two and a half"
|
||||
- `0.3` → "point three"
|
||||
- **Critical**: Prevents numbers appearing as text in generated images
|
||||
|
||||
### 3. Dual Prompt Formats
|
||||
- **Simple Prompt**: Nanobanan-style natural language (English only)
|
||||
- **Professional Prompt**: v7-style with Chinese cinematography terms + "Next Scene:" prefix
|
||||
- **Description**: Human-readable summary with emojis
|
||||
|
||||
### 4. Parameter Validation
|
||||
- Wide Shot + Shallow DOF → ⚠️ Warning
|
||||
- Macro Lens + Wide Shot → ⚠️ Warning
|
||||
- Telephoto + Wide FOV → ⚠️ Warning
|
||||
|
||||
### 5. Multi-Language Support
|
||||
- **English Only**: Simple natural descriptions
|
||||
- **Chinese (Best)**: Full Chinese cinematography terms
|
||||
- **Hybrid**: Chinese camera terms + English details (best for dx8152 LoRAs)
|
||||
|
||||

|
||||
- "An eye-level close-up of the watch, taken from..."
|
||||
- Perfect for beginners and general use
|
||||
|
||||
2. **professional_prompt** (STRING): v7-style directive with Chinese
|
||||
- "Next Scene: 将镜头转为人像镜头(85mm), 近景构图..."
|
||||
- Optimized for dx8152 LoRAs and professional results
|
||||
|
||||
3. **description** (STRING): Human-readable summary
|
||||
- Shows all parameters, auto-calculations, and warnings
|
||||
- Useful for debugging and understanding node behavior
|
||||
|
||||

## Testing Workflow
|
||||
|
||||
**Recommended testing steps:**
|
||||
|
||||
1. Load node in ComfyUI
|
||||
2. For each test case above:
|
||||
- Set parameters as listed
|
||||
- Check simple_prompt output matches expected
|
||||
- Check professional_prompt output matches expected
|
||||
- Verify no syntax errors in generated prompts
|
||||
3. Test parameter validation:
|
||||
- Set Wide Shot + Shallow DOF → Should show warning
|
||||
- Set Macro Lens + Wide Shot → Should show warning
|
||||
4. Test auto-calculations:
|
||||
- Change shot size → Distance/Lens/DOF should update automatically
|
||||
5. Test number-to-words:
|
||||
- Verify no numeric "4.5" appears in prompts, only "four and a half"

# Custom Details Tooltip Enhancement
|
||||
|
||||
## Summary
|
||||
|
||||
Enhanced the `custom_details` parameter tooltip in Cinematography Prompt Builder to provide clear examples of compositional specifics that go beyond the 5 core ingredients (Subject, Shot Type, Angle, Focus/DOF, Style).
|
||||
|
||||
---
|
||||
|
||||
## Changes Made
|
||||
|
||||
### File: nodes/camera/cinematography_prompt_builder.py
|
||||
|
||||
**Lines 274-284**: Updated `custom_details` tooltip
|
||||
|
||||
**Before:**
|
||||
```python
|
||||
"custom_details": ("STRING", {
|
||||
"default": "",
|
||||
"multiline": True,
|
||||
"tooltip": "Add any custom details (e.g., 'showing dial and hands', 'with marble backsplash visible')"
|
||||
}),
|
||||
```
|
||||
|
||||
**After:**
|
||||
```python
|
||||
"custom_details": ("STRING", {
|
||||
"default": "",
|
||||
"multiline": True,
|
||||
"tooltip": "Add compositional specifics beyond the 5 ingredients. Examples:\n"
|
||||
"• 'The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above'\n"
|
||||
"• 'focusing on the intricate details of a single burner and the cast-iron grate'\n"
|
||||
"• 'showing dial and hands clearly'\n"
|
||||
"• 'The vantage point is inches away, creating an extremely shallow depth of field'\n"
|
||||
"• 'dissolves into a soft, blurred bokeh'\n"
|
||||
"• 'The lighting is bright and even, keeping the entire area in sharp focus'"
|
||||
}),
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Why This Matters
|
||||
|
||||
### Problem
|
||||
The 5-ingredient formula (Subject, Shot Type, Angle, Focus/DOF, Style) provides the **foundation** for camera prompts, but working examples show that **rich compositional details** make the difference between good and great results.
|
||||
|
||||
**Example:**
|
||||
|
||||
**5 Ingredients Only:**
|
||||
```
|
||||
An eye-level full shot of the green stove, taken from a vantage point four and a half meters away, with deep depth of field, in clean and modern style
|
||||
```
|
||||
|
||||
**5 Ingredients + Custom Details:**
|
||||
```
|
||||
An eye-level full shot of the green stove, taken from a vantage point four and a half meters away, with deep depth of field, in clean and modern style. The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above. The lighting is bright and even, keeping the entire cooking area in sharp focus.
|
||||
```
|
||||
|
||||
The second prompt provides:
|
||||
- **Composition guidance** ("entire stove is centered")
|
||||
- **Context inclusion** ("marble backsplash, range hood above")
|
||||
- **Lighting specifics** ("bright and even")
|
||||
- **Focus distribution** ("entire cooking area in sharp focus")
|
||||
|
||||
---
|
||||
|
||||
## Examples from Working Prompts
|
||||
|
||||
All examples are taken directly from the working prompts documented in [CAMERA_PROMPTING_GUIDE.md](CAMERA_PROMPTING_GUIDE.md):
|
||||
|
||||
### Example 1: Full Shot - Compositional Framing
|
||||
**Custom Detail:**
|
||||
```
|
||||
The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above
|
||||
```
|
||||
|
||||
**Why It Works:**
|
||||
- Specifies exact subject placement ("centered in the frame")
|
||||
- Lists contextual elements to include ("marble backsplash", "range hood")
|
||||
- Ensures comprehensive view ("entire stove")
|

||||
|
||||
### Example 2: Extreme Macro - Focus Control
|
||||
**Custom Detail:**
|
||||
```
|
||||
focusing on the intricate details of a single burner and the cast-iron grate
|
||||
```
|
||||
|
||||
**Why It Works:**
|
||||
- Specifies what to isolate ("single burner")
|
||||
- Emphasizes detail level ("intricate details")
|
||||
- Names specific components ("cast-iron grate")
|
||||
|
||||
---
|
||||
|
||||
### Example 3: Extreme Macro - Bokeh Description
|
||||
**Custom Detail:**
|
||||
```
|
||||
The vantage point is inches away, creating an extremely shallow depth of field where only the front edge of the burner is in sharp focus, and the rest of the stove and kitchen dissolves into a soft, blurred bokeh
|
||||
```
|
||||
|
||||
**Why It Works:**
|
||||
- Reinforces proximity ("inches away")
|
||||
- Describes focus falloff precisely ("only the front edge")
|
||||
- Uses evocative language for blur ("dissolves into soft, blurred bokeh")
|
||||
|
||||
---
|
||||
|
||||
### Example 4: Full Shot - Lighting Details
|
||||
**Custom Detail:**
|
||||
```
|
||||
The lighting is bright and even, keeping the entire area in sharp focus
|
||||
```
|
||||
|
||||
**Why It Works:**
|
||||
- Specifies lighting quality ("bright and even")
|
||||
- Connects lighting to focus ("keeping entire area in sharp focus")
|
||||
|
||||
---
|
||||
|
||||
### Example 5: Watch Detail - Component Naming
|
||||
**Custom Detail:**
|
||||
```
|
||||
showing dial and hands clearly
|
||||
```
|
||||
|
||||
**Why It Works:**
|
||||
- Names specific components to emphasize
|
||||
- Ensures clarity ("clearly")
|
||||
|
||||
---
|
||||
|
||||
## How Users Should Use Custom Details
|
||||
|
||||
### 1. Start with the 5 Ingredients (Foundation)
|
||||
Set these parameters in the node:
|
||||
- **Subject:** "the green stove"
|
||||
- **Shot Type:** "Full Shot (FS)"
|
||||
- **Angle:** "Eye Level"
|
||||
- **Depth of Field:** "Deep"
|
||||
- **Style:** "Clean/Modern"
|
||||
|
||||
### 2. Add Custom Details (Enhancement)
|
||||
In the `custom_details` field, add compositional specifics:
|
||||
```
|
||||
The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above. The lighting is bright and even, keeping the entire cooking area in sharp focus.
|
||||
```
|
||||
|
||||
### 3. Result
|
||||
The node generates a complete prompt combining both:
|
||||
```
|
||||
An eye-level full shot of the green stove, taken from a vantage point four and a half meters away, with deep depth of field keeping everything in focus, in clean and modern style. The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above. The lighting is bright and even, keeping the entire cooking area in sharp focus.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Categories of Custom Details
|
||||
|
||||
The tooltip examples cover 6 essential categories:
|
||||
|
||||
### 1. Compositional Framing
|
||||

|
||||
"The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above"
|
||||
```
|
||||
**Use for:** Subject placement, contextual elements, framing guidance
|
||||
|
||||
---
|
||||
|
||||
### 2. Detail Isolation
|
||||
```
|
||||
"focusing on the intricate details of a single burner and the cast-iron grate"
|
||||
```
|
||||
**Use for:** Macro shots, close-ups, component emphasis
|
||||
|
||||
---
|
||||

|
||||
|
||||
---
|
||||
|
||||
### 4. Vantage Point Reinforcement
|
||||

||||
"The vantage point is inches away, creating an extremely shallow depth of field"
|
||||
```
|
||||
**Use for:** Extreme close-ups, macro, proximity emphasis
|
||||
|
||||
---
|
||||
|
||||
### 5. Bokeh Description
|
||||

# Horizontal Angle + Perspective Correction Implementation
|
||||
|
||||
## Summary
|
||||
|
||||
Added two powerful new features to the Cinematography Prompt Builder to enable precise architectural photography control:
|
||||
|
||||
1. **Horizontal Angle** - Control camera position around the object (0°, 15°, 30°, 45°, 90°, 180°)
|
||||
2. **Perspective Correction** - Keep vertical lines straight for professional architectural photography
|
||||
|
||||
**Implementation Date:** 2025-01-07
|
||||
**Version:** v2.4.0 (pending release)
|
||||
|
||||
---
|
||||
|
||||
## What Was Added
|
||||
|
||||
### 1. Horizontal Angle Parameter
|
||||
|
||||
**Location:** [cinematography_prompt_builder.py:138-157](nodes/camera/cinematography_prompt_builder.py#L138-L157)
|
||||
|
||||
```python
|
||||
"horizontal_angle": ([
|
||||
"Front View (0°)",
|
||||
"Angled Left 15°",
|
||||
"Angled Left 30°",
|
||||
"Angled Left 45°",
|
||||
"Side Left (90°)",
|
||||
"Back View (180°)",
|
||||
"Side Right (90°)",
|
||||
"Angled Right 45°",
|
||||
"Angled Right 30°",
|
||||
"Angled Right 15°"
|
||||
], {
|
||||
"default": "Front View (0°)",
|
||||
"tooltip": "Horizontal camera position around the object:\n"
|
||||
"• Front (0°) = Straight-on view\n"
|
||||
"• Angled (15-45°) = Corner/three-quarter view\n"
|
||||
"• Side (90°) = Profile view\n"
|
||||
"• Back (180°) = Rear view"
|
||||
})
|
||||
```
|
||||
|
||||
**Purpose:** Allows users to control the camera's orbital position around the subject, from straight-on frontal views to side profiles and rear views.
|
||||
|
||||
---
|
||||
|
||||
### 2. Perspective Correction Parameter
|
||||
|
||||
**Location:** [cinematography_prompt_builder.py:223-233](nodes/camera/cinematography_prompt_builder.py#L223-L233)
|
||||
|
||||
```python
|
||||
"perspective_correction": ([
|
||||
"Natural (Standard Lens)",
|
||||
"Architectural (Keep Verticals Straight)",
|
||||
"Tilt-Shift (Full Perspective Control)"
|
||||
], {
|
||||
"default": "Natural (Standard Lens)",
|
||||
"tooltip": "Control vertical line convergence for architectural photography:\n"
|
||||
"• Natural = Standard perspective with natural converging lines\n"
|
||||
"• Architectural = Keep vertical lines parallel (requires eye-level framing)\n"
|
||||
"• Tilt-Shift = Professional perspective correction with selective focus plane"
|
||||
})
|
||||
```
|
||||
|
||||
**Purpose:** Enables professional architectural photography with straight vertical lines, preventing converging lines and keystoning distortion.
|
||||
|
||||
---
|
||||
|
||||
## Helper Methods Added
|
||||
|
||||
### 1. `_get_horizontal_angle_description()`
|
||||
|
||||
**Location:** [cinematography_prompt_builder.py:422-460](nodes/camera/cinematography_prompt_builder.py#L422-L460)
|
||||
|
||||
Converts horizontal angle selections into natural language descriptions in both English and Chinese:
|
||||
|
||||
**Examples:**
|
||||
- "Front View (0°)" → `("", "")` (no explicit mention needed)
|
||||
- "Angled Left 30°" → `("from thirty degrees to the left for a corner perspective", "从左侧30度拍摄,呈现转角视角")`
|
||||
- "Side Left (90°)" → `("from the left side for a profile view", "从左侧拍摄,呈现侧面视角")`
|
||||
|
||||
---
|
||||
|
||||
### 2. `_get_perspective_correction_prompting()`
|
||||
|
||||
**Location:** [cinematography_prompt_builder.py:462-481](nodes/camera/cinematography_prompt_builder.py#L462-L481)
|
||||
|
||||
Generates perspective correction guidance text:
|
||||
|
||||
**Examples:**
|
||||
|
||||
**Architectural Mode:**
|
||||
```
|
||||
English: "with careful framing to keep all vertical lines parallel and prevent perspective distortion,
|
||||
maintaining straight architectural lines throughout the frame"
|
||||
Chinese: "保持所有垂直线平行,防止透视畸变,确保建筑线条笔直"
|
||||
```
|
||||
|
||||
**Tilt-Shift Mode:**
|
||||
```
|
||||
English: "using a tilt-shift lens for perspective correction to keep all vertical lines perfectly parallel,
|
||||
with precise control over the focus plane and no keystoning distortion"
|
||||
Chinese: "使用移轴镜头进行透视校正,保持所有垂直线完美平行,精确控制焦平面,无梯形失真"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Updated Methods
|
||||
|
||||
### 1. `validate_parameters()` - Enhanced Validation
|
||||
|
||||
**Location:** [cinematography_prompt_builder.py:483-514](nodes/camera/cinematography_prompt_builder.py#L483-L514)
|
||||
|
||||
**Added validation rule:**
|
||||
```python
|
||||
# Perspective correction + non-level camera angle conflict
|
||||
if perspective_correction in ["Architectural (Keep Verticals Straight)",
|
||||
"Tilt-Shift (Full Perspective Control)"]:
|
||||
if camera_angle in ["High Angle (looking down)", "Low Angle (looking up)",
|
||||
"Bird's Eye View (overhead)", "Worm's Eye View (ground up)"]:
|
||||
warnings.append(
|
||||
"⚠️ Perspective correction requires eye-level camera angle. "
|
||||
"Vertical lines will converge with tilted camera positions. "
|
||||
"Use 'Eye Level' or 'Shoulder Level' for straight verticals."
|
||||
)
|
||||
```
|
||||
|
||||
**Why this matters:** You cannot maintain straight vertical lines if the camera is tilted up or down. This validation warns users about incompatible parameter combinations.
|
||||
|
||||
---
|
||||
|
||||
### 2. `generate_cinematography_prompt()` - Function Signature Update
|
||||
|
||||
**Location:** [cinematography_prompt_builder.py:583-593](nodes/camera/cinematography_prompt_builder.py#L583-L593)
|
||||
|
||||
**Added parameters:**
|
||||
```python
|
||||
def generate_cinematography_prompt(self, target_subject, shot_type, camera_angle,
|
||||
depth_of_field, style_mood, prompt_language,
|
||||
horizontal_angle="Front View (0°)", # NEW
|
||||
lens_type_override="Auto (from shot size)",
|
||||
perspective_correction="Natural (Standard Lens)", # NEW
|
||||
camera_movement="Static (No Movement)",
|
||||
...
|
||||
```
|
||||
|
||||
**Auto-Selection Logic** (Lines 585-591):
|
||||
```python
|
||||
# Determine lens (with tilt-shift auto-selection for perspective correction)
|
||||
if perspective_correction == "Tilt-Shift (Full Perspective Control)":
|
||||
lens_type = "Tilt-Shift (Perspective Control)" # Auto-select tilt-shift lens
|
||||
elif lens_type_override == "Auto (from shot size)":
|
||||
lens_type = shot_defaults["lens"]
|
||||
else:
|
||||
lens_type = lens_type_override
|
||||
```
|
||||
|
||||
**When "Tilt-Shift (Full Perspective Control)" is selected, the node automatically uses a tilt-shift lens regardless of lens_type_override setting.**
|
||||
|
||||
---
|
||||
|
||||
### 3. `_generate_simple_prompt()` - Enhanced Prompt Generation
|
||||
|
||||
**Location:** [cinematography_prompt_builder.py:629-679](nodes/camera/cinematography_prompt_builder.py#L629-L679)
|
||||
|
||||
**Added sections:**
|
||||
```python
|
||||
# Horizontal angle (if not front view)
|
||||
if horizontal_desc_en:
|
||||
parts.append(f"positioned {horizontal_desc_en}")
|
||||
|
||||
# Perspective correction (if enabled)
|
||||
if perspective_desc_en:
|
||||
parts.append(perspective_desc_en)
|
||||
```
|
||||
|
||||
**Example Output Comparison:**
|
||||
|
||||
**Before (without new features):**
|
||||
```
|
||||
An eye-level full shot of modern kitchen, taken from a vantage point four and a half meters away,
|
||||
with deep depth of field keeping everything in focus, in architectural style
|
||||
```
|
||||
|
||||
**After (with horizontal angle + perspective correction):**
|
||||
```
|
||||
An eye-level full shot of modern kitchen, taken from a vantage point four and a half meters away,
|
||||
positioned from thirty degrees to the left for a corner perspective, with careful framing to keep
|
||||
all vertical lines parallel and prevent perspective distortion, maintaining straight architectural
|
||||
lines throughout the frame, with deep depth of field keeping everything in focus, in architectural style
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 4. `_generate_professional_prompt()` - Chinese Translation Support
|
||||
|
||||
**Location:** [cinematography_prompt_builder.py:711-806](nodes/camera/cinematography_prompt_builder.py#L711-L806)
|
||||
|
||||
**Added horizontal angle + perspective to Chinese section:**
|
||||
```python
|
||||
# Horizontal angle (if not front view)
|
||||
if horizontal_desc_zh:
|
||||
chinese_parts.append(horizontal_desc_zh)
|
||||
|
||||
# Perspective correction (if enabled)
|
||||
if perspective_desc_zh:
|
||||
chinese_parts.append(perspective_desc_zh)
|
||||
```
|
||||
|
||||
**Added to English section:**
|
||||
```python
|
||||
base = f"Next Scene: Change to {lens}, {shot_abbreviation} framing, {angle} viewing {subject}"
|
||||
if horizontal_desc_en:
|
||||
base += f", positioned {horizontal_desc_en}"
|
||||
if perspective_desc_en:
|
||||
base += f", {perspective_desc_en}"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 5. `_get_cinematography_system_prompt()` - Architectural Guidance
|
||||
|
||||
**Location:** [cinematography_prompt_builder.py:516-581](nodes/camera/cinematography_prompt_builder.py#L516-L581)
|
||||
|
||||
**Added architectural perspective guidance:**
|
||||
```python
|
||||
# Architectural perspective guidance (appended to all modes if enabled)
|
||||
architectural_guidance = ""
|
||||
if perspective_correction in ["Architectural (Keep Verticals Straight)", "Tilt-Shift (Full Perspective Control)"]:
|
||||
architectural_guidance = (
|
||||
" IMPORTANT: Maintain parallel vertical lines in architectural photography. "
|
||||
"Keep the camera level (no upward or downward tilt) to prevent converging verticals and keystoning. "
|
||||
"All vertical architectural elements (walls, doors, columns, windows) must remain straight and parallel in the frame. "
|
||||
"This requires eye-level camera positioning without vertical angle deviation."
|
||||
)
|
||||
```
|
||||
|
||||
This guidance is **automatically appended** to all three system prompt modes (Professional, Research-Validated, Simple/Beginner) when perspective correction is enabled.
|
||||
|
||||

- **Lens:** Auto-selected to `Tilt-Shift (Perspective Control)`
|
||||
|
||||
**Generated Simple Prompt:**
|
||||
```
|
||||
An eye-level full shot of architectural exterior facade, taken from a vantage point four and a half meters away,
|
||||
positioned from the left side for a profile view, using a tilt-shift lens for perspective correction to keep
|
||||
all vertical lines perfectly parallel, with precise control over the focus plane and no keystoning distortion,
|
||||
with deep depth of field, in architectural style
|
||||
```
|
||||
|
||||
**Key Features:**
|
||||
- ✅ Automatic tilt-shift lens selection
|
||||
- ✅ Side profile positioning
|
||||
- ✅ Professional perspective correction language
|
||||
- ✅ Focus plane control mentioned
|

### Example 4: Invalid Combination - Validation Warning
|
||||
|
||||
**Parameters:**
|
||||
- Subject: `building`
|
||||
- Shot Type: `Full Shot (FS)`
|
||||
- **Camera Angle: `Low Angle (looking up)`** ⚠️
|
||||
- Horizontal Angle: `Front View (0°)`
|
||||
- **Perspective Correction: `Architectural (Keep Verticals Straight)`** ⚠️
|
||||
|
||||
**Validation Warning:**
|
||||
```
|
||||
⚠️ Perspective correction requires eye-level camera angle. Vertical lines will converge with
|
||||
tilted camera positions. Use 'Eye Level' or 'Shoulder Level' for straight verticals.
|
||||
```
|
||||
|
||||
**Why:** You cannot keep vertical lines parallel when the camera is tilted upward (low angle). The validation system warns users about this incompatibility.
|
||||

|
||||
|
||||
## Perspective Correction Modes Explained
|
||||
|
||||
### Mode 1: Natural (Standard Lens) - Default
|
||||
|
||||
**When to use:** General photography where natural perspective convergence is acceptable.
|
||||
|
||||
**Characteristics:**
|
||||
- Vertical lines converge naturally (especially with wide-angle lenses)
|
||||
- Standard perspective rendering
|
||||
- No special corrections applied
|
||||
|
||||
**Generated Prompt:**
|
||||
```
|
||||
An eye-level full shot of kitchen, taken from a vantage point four and a half meters away
|
||||
```
|
||||
(No perspective guidance added)
|
||||
|
||||
---
|
||||
|
||||
### Mode 2: Architectural (Keep Verticals Straight) - Recommended for Interior Design
|
||||
|
||||
**When to use:** Professional architectural photography, interior design visualization, real estate photography.
|
||||
|
||||
**Characteristics:**
|
||||
- Emphasizes parallel vertical lines
|
||||
- Prevents keystoning
|
||||
- Requires eye-level camera positioning
|
||||
- Standard architectural photography technique
|
||||
|
||||
**Generated Prompt:**
|
||||
```
|
||||
An eye-level full shot of kitchen, taken from a vantage point four and a half meters away,
|
||||
with careful framing to keep all vertical lines parallel and prevent perspective distortion,
|
||||
maintaining straight architectural lines throughout the frame
|
||||
```
|
||||
|
||||
**System Prompt Guidance:**
|
||||
```
|
||||
IMPORTANT: Maintain parallel vertical lines in architectural photography. Keep the camera level
|
||||
(no upward or downward tilt) to prevent converging verticals and keystoning.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Mode 3: Tilt-Shift (Full Perspective Control) - Professional
|
||||
|
||||
**When to use:** Professional architectural photography requiring both perspective correction AND selective focus control.
|
||||
|
||||
**Characteristics:**
|
||||
- Uses tilt-shift lens (auto-selected)
|
||||
- Full perspective correction
|
||||
- Selective focus plane control
|
||||
- Zero keystoning distortion
|
||||
- Most professional option
|
||||
|
||||
**Generated Prompt:**
|
||||
```
|
||||
An eye-level full shot of kitchen, taken from a vantage point four and a half meters away,
|
||||
using a tilt-shift lens for perspective correction to keep all vertical lines perfectly parallel,
|
||||
with precise control over the focus plane and no keystoning distortion
|
||||
```
|
||||
|
||||
**Auto-Selection:** Lens automatically changes to "Tilt-Shift (Perspective Control)" regardless of lens_type_override setting.

## Horizontal Angle Options Explained
|
||||
|
||||
| Angle | Description | Use Case | Natural Language Output |
|
||||
|-------|-------------|----------|------------------------|
|
||||
| **Front View (0°)** | Straight-on, face-to-face | Product photography, symmetrical compositions | (no explicit mention) |
|
||||
| **Angled Left/Right 15°** | Slight offset | Subtle three-dimensionality | "from fifteen degrees to the left/right" |
|
||||
| **Angled Left/Right 30°** | Corner perspective | Interior corners, three-quarter views | "from thirty degrees to the left/right for a corner perspective" |
|
||||
| **Angled Left/Right 45°** | Strong three-quarter | Classic three-quarter product view | "from forty-five degrees to the left/right for a three-quarter view" |
|
||||
| **Side Left/Right (90°)** | Profile view | Architectural elevations, profiles | "from the left/right side for a profile view" |
|
||||
| **Back View (180°)** | Rear view | Back details, reverse angles | "from behind the subject" |

|
||||
### Parameter Order in Function Signature
|
||||
|
||||
```python
|
||||
def generate_cinematography_prompt(
|
||||
self,
|
||||
# Core 5 ingredients (required)
|
||||
target_subject,
|
||||
shot_type,
|
||||
camera_angle,
|
||||
depth_of_field,
|
||||
style_mood,
|
||||
prompt_language,
|
||||
|
||||
# NEW: Horizontal positioning (optional)
|
||||
horizontal_angle="Front View (0°)",
|
||||
|
||||
# Professional enhancements (optional)
|
||||
lens_type_override="Auto (from shot size)",
|
||||
|
||||
# NEW: Perspective control (optional)
|
||||
perspective_correction="Natural (Standard Lens)",
|
||||
|
||||
camera_movement="Static (No Movement)",
|
||||
lighting_style="Auto/Natural",
|
||||
material_detail_preset="None (Manual entry)",
|
||||
photography_quality_preset="None (Manual entry)",
|
||||
custom_details="",
|
||||
show_advanced_info=False
|
||||
):
|
||||
```
|
||||
|
||||
**Design Rationale:**
|
||||
1. Core 5 ingredients remain first (required parameters)
|
||||
2. `horizontal_angle` added after core parameters (new positioning control)
|
||||
3. `perspective_correction` added after lens override (architectural enhancement)
|
||||
4. All new parameters have sensible defaults (backwards compatible)
|
||||
|
||||
---
|
||||
|
||||
### Validation Logic Flow
|
||||
|
||||
```python
|
||||
1. User selects parameters
|
||||
2. Node calls validate_parameters(shot_type, dof, lens_type, camera_angle, perspective_correction)
|
||||
3. Validation checks:
|
||||
- Wide shot + Shallow DOF → Warning
|
||||
- Macro lens + Wide shot → Warning
|
||||
- Telephoto + Wide shot → Warning
|
||||
- **Perspective correction + Non-level angle → Warning** ⭐ NEW
|
||||
4. Warnings displayed in description output
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Prompt Generation Flow
|
||||
|
||||
```python
|
||||
1. Get shot defaults (distance, lens, DOF)
|
||||
2. Auto-select tilt-shift lens if perspective_correction == "Tilt-Shift"
|
||||
3. Validate parameters
|
||||
4. Generate Simple Prompt:
|
||||
- Opening (angle + shot + subject)
|
||||
- Distance (meters/centimeters)
|
||||
- **Horizontal angle (if not front view)** ⭐ NEW
|
||||
- **Perspective correction (if enabled)** ⭐ NEW
|
||||
- DOF description
|
||||
- Style/Mood
|
||||
- Lighting
|
||||
- Custom details
|
||||
5. Generate Professional Prompt (Chinese + English with same additions)
|
||||
6. Generate System Prompt (with architectural guidance if enabled)
|
||||
7. Generate Description (with warnings)
|
||||
8. Return (simple_prompt, professional_prompt, system_prompt, description)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Compatibility
|
||||
|
||||
### Backwards Compatibility
|
||||
|
||||
✅ **Fully backwards compatible** - All new parameters have defaults:
|
||||
- `horizontal_angle="Front View (0°)"` (no explicit mention in prompt)
|
||||
- `perspective_correction="Natural (Standard Lens)"` (no special corrections)
|
||||
|
||||
**Existing workflows** using the Cinematography Prompt Builder will continue working without modification.
|
||||
|
||||
**New workflows** can leverage the new parameters for enhanced control.

|
||||
|
||||
### Language Support
|
||||
|
||||
| Language Mode | Horizontal Angle | Perspective Correction |
|
||||
|---------------|------------------|------------------------|
|
||||
| English (Simple & Clear) | ✅ Full support | ✅ Full support |
|
||||
| Chinese (Best for dx8152 LoRAs) | ✅ Chinese translations | ✅ Chinese translations |
|
||||
| Hybrid (Chinese + English) | ✅ Both languages | ✅ Both languages |
|
||||
|
||||
---
|
||||
|
||||
## Benefits
|
||||
|
||||
### 1. Precise Camera Positioning
|
||||
|
||||
Users can now control:
|
||||
- **Vertical angle** (existing camera_angle parameter)
|
||||
- **Horizontal angle** (NEW horizontal_angle parameter)
|
||||
- **Distance** (shot size determines distance)
|
||||
|
||||
This provides **full 3D camera positioning control** around the subject.
|
||||
|
||||
---
|
||||
|
||||
### 2. Professional Architectural Photography
|
||||
|
||||
The perspective correction feature enables:
|
||||
- ✅ Straight vertical lines (no converging lines)
|
||||
- ✅ No keystoning distortion
|
||||
- ✅ Professional architectural presentation
|
||||
- ✅ Real estate photography standards
|
||||
- ✅ Interior design visualization quality
|
||||
|
||||
---
|
||||
|
||||
### 3. Research-Validated Approach
|
||||
|
||||
**Horizontal angles use natural language:**
|
||||
- "from thirty degrees to the left" (NOT "rotate 30 degrees")
|
||||
- Aligns with research finding that **distance-based positioning is more reliable than degree-based**
|
||||
|
||||
**Perspective correction is explicit:**
|
||||
- Clear guidance in prompts
|
||||
- System prompt reinforcement
|
||||
- Validation warnings for incompatible settings
|
||||
|
||||
---
|
||||
|
||||
### 4. User-Friendly Design
|
||||
|
||||
- **Clear tooltips** explain each option
|
||||
- **Validation warnings** prevent mistakes
|
||||
- **Auto-selection** (tilt-shift lens when needed)
|
||||
- **Sensible defaults** (Front View, Natural perspective)
|
||||
- **Progressive enhancement** (start simple, add complexity as needed)
|
||||

# Prompt Format Fixes - Natural Language Improvements
|
||||
|
||||
## Summary
|
||||
|
||||
Fixed 3 critical bugs in the Simple Prompt generation to match natural language style of working examples.
|
||||
|
||||
---
|
||||
|
||||
## 🐛 Bugs Fixed
|
||||
|
||||
### **Bug 1: Using Abbreviations Instead of Full Shot Names**
|
||||
|
||||
**Before (WRONG):**
|
||||
```
|
||||
A shoulder level ecu of stove oven...
|
||||
```
|
||||
|
||||
**After (CORRECT):**
|
||||
```
|
||||
An eye-level extreme close-up of stove oven...
|
||||
```
|
||||
|
||||
**Fix:** Added `get_shot_full_name()` method to return spelled-out shot types instead of abbreviations.
|
||||
|
||||
---
|
||||
|
||||
### **Bug 2: Vague Distance Descriptions**
|
||||
|
||||
**Before (WRONG):**
|
||||
```
|
||||
...taken from very close distance...
|
||||
```
|
||||
|
||||
**After (CORRECT):**
|
||||
```
|
||||
...taken from a vantage point thirty centimeters away...
|
||||
```
|
||||
|
||||
**Fix:** Always use specific distance in natural language (centimeters for <1m, meters for ≥1m).
|
||||
|
||||
---
|
||||
|
||||
### **Bug 3: Incorrect Angle Names**
|
||||
|
||||
**Before (WRONG):**
|
||||
```
|
||||
A shoulder level...
|
||||
```
|
||||
(Note: "shoulder level" doesn't exist in cinematography)
|
||||
|
||||
**After (CORRECT):**
|
||||
```
|
||||
An eye-level...
|
||||
```
|
||||
|
||||
**Fix:** Proper angle cleaning now preserves standard cinematography terms.

||||
|
||||
### 1. Added `get_shot_full_name()` Method (Lines 369-381)
|
||||
|
||||
```python
|
||||
def get_shot_full_name(self, shot_type):
|
||||
"""Extract full natural language name from shot type (not abbreviation)"""
|
||||
full_names = {
|
||||
"Extreme Close-Up (ECU)": "extreme close-up",
|
||||
"Close-Up (CU)": "close-up",
|
||||
"Medium Close-Up (MCU)": "medium close-up",
|
||||
"Medium Shot (MS)": "medium shot",
|
||||
"Medium Long Shot (MLS)": "medium long shot",
|
||||
"Full Shot (FS)": "full shot",
|
||||
"Wide Shot (WS)": "wide shot",
|
||||
"Extreme Wide Shot (EWS)": "extreme wide shot"
|
||||
}
|
||||
return full_names.get(shot_type, shot_type.lower().split("(")[0].strip())
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. Updated `_generate_simple_prompt()` (Lines 524-546)
|
||||
|
||||
**Changed from:**
|
||||
```python
|
||||
# Get shot abbreviation
|
||||
shot_abbr = self.get_shot_abbreviation(shot_type).lower() # Returns "ecu"
|
||||
```
|
||||
|
||||
**To:**
|
||||
```python
|
||||
# Get FULL shot name (not abbreviation) for natural language
|
||||
shot_full = self.get_shot_full_name(shot_type) # Returns "extreme close-up"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. Fixed Distance Formatting (Lines 539-546)
|
||||
|
||||
**Changed from:**
|
||||
```python
|
||||
# Distance: "taken from [distance] away"
|
||||
if distance < 0.5:
|
||||
parts.append("taken from very close distance") # VAGUE
|
||||
elif distance < 1.0:
|
||||
parts.append(f"taken from close distance") # VAGUE
|
||||
else:
|
||||
parts.append(f"taken from a vantage point {distance_words} meters away")
|
||||
```
|
||||
|
||||
**To:**
|
||||
```python
|
||||
# Distance: "taken from a vantage point [distance] meters away" (ALWAYS specific)
|
||||
# For distances under 1 meter, use "centimeters" for better readability
|
||||
if distance < 1.0:
|
||||
cm_distance = int(distance * 100)
|
||||
cm_words = self._int_to_words(cm_distance)
|
||||
parts.append(f"taken from a vantage point {cm_words} centimeters away")
|
||||
else:
|
||||
parts.append(f"taken from a vantage point {distance_words} meters away")
|
||||
```
|
||||
|
||||
**Result:**
|
||||
- 0.3m → "thirty centimeters away" (clear and natural)
|
||||
- 0.8m → "eighty centimeters away" (clear and natural)
|
||||
- 2.5m → "two and a half meters away" (clear and natural)
|
||||
- 4.5m → "four and a half meters away" (clear and natural)
|
||||
|
||||
---
|
||||
|
||||
## ✅ Verification
|
||||
|
||||
### Distance Conversion Examples
|
||||
|
||||
| Shot Type | Distance | Number | Natural Language Output |
|
||||
|-----------|----------|--------|------------------------|
|
||||
| ECU | 0.3m | 30cm | "thirty centimeters away" |
|
||||
| CU | 0.8m | 80cm | "eighty centimeters away" |
|
||||
| MCU | 1.2m | 1.2m | "one point two meters away" |
|
||||
| MS | 2.5m | 2.5m | "two and a half meters away" |
|
||||
| MLS | 3.5m | 3.5m | "three and a half meters away" |
|
||||
| FS | 4.5m | 4.5m | "four and a half meters away" |
|
||||
| WS | 6.5m | 6.5m | "six and a half meters away" |
|
||||
| EWS | 10.0m | 10.0m | "ten meters away" |
|
||||
|
||||
---
|
||||
|
||||
## 🎯 Result
|
||||
|
||||
Your test output should now be:
|
||||
|
||||
**BEFORE (Broken):**
|
||||
```
|
||||
A shoulder level ecu of stove oven, taken from very close distance, with very shallow depth of field creating blurred background, in architectural style
|
||||
```
|
||||
|
||||
**AFTER (Fixed):**
|
||||
```
|
||||
An eye-level extreme close-up of stove oven, taken from a vantage point thirty centimeters away, with very shallow depth of field creating blurred background, in architectural style
|
||||
```
|
||||
|
||||
**Comparison with Working Example Format:**
|
||||
```
|
||||
An eye-level full shot of the green stove, taken from a vantage point 4 meters away. The entire stove is centered in the frame, clearly showing it, the marble backsplash, and the range hood above. The lighting is bright and even, keeping the entire cooking area in sharp focus.
|
||||
```
|
||||
|
||||
**Match:** ✅ STRUCTURE MATCHES - Natural language, spelled-out shot types, specific distances
|
||||

# Session Updates - v2.4.1 (2025-01-07)
|
||||
|
||||
## Overview
|
||||
This document summarizes all changes made during the v2.4.1 development session.
|
||||
|
||||
## Package Cleanup
|
||||
**Removed redundant GRAG sampler** - The full GRAG Advanced Sampler is now maintained in the separate [ComfyUI-GRAG-ArchAi3D](https://github.com/amir84ferdos/ComfyUI-GRAG-ArchAi3D) repository. This package retains GRAG utility nodes (GRAG Modifier, GRAG Encoder) for conditioning metadata injection.
|
||||

|
||||
|
||||
## 1. Auto-Facing Feature Added to Cinematography Prompt Builder
|
||||
|
||||
### What Changed
|
||||
Added `auto_facing` parameter to **Cinematography Prompt Builder** node, previously only available in Object Focus Camera v7.
|
||||
|
||||
### Why Important
|
||||
User insight: "i know it is important if you merg it to prompt at begiing it will have more affect base on my experince"
|
||||
|
||||
Based on vision-language model attention mechanisms, placing the facing directive at the **beginning** of prompts provides maximum attention weight and effectiveness.
|
||||
|
||||
### Implementation Details
|
||||
|
||||
**File**: `nodes/camera/cinematography_prompt_builder.py`
|
||||
|
||||
1. **Added Parameter** (Lines 159-165):
|
||||
```python
|
||||
"auto_facing": ("BOOLEAN", {
|
||||
"default": True,
|
||||
"tooltip": "Automatically face camera toward target subject (recommended for object photography).\n"
|
||||
"• True = Camera points directly at subject from chosen angle\n"
|
||||
"• False = Camera positioned at angle but may not face subject directly"
|
||||
}),
|
||||
```
|
||||
|
||||
2. **Simple Prompt Generation** (Lines 685-688):
|
||||
```python
|
||||
# AUTO-FACING: Add at the VERY BEGINNING for maximum attention weight
|
||||
# Only add if enabled AND not front view (front view already implies facing)
|
||||
if auto_facing and horizontal_angle != "Front View (0°)":
|
||||
parts.append(f"Facing {subject} directly")
|
||||
```
|
||||
|
||||
3. **Professional Prompt Generation** (Lines 757-763):
|
||||
```python
|
||||
# AUTO-FACING: Add at BEGINNING for maximum attention (before "Next Scene:")
|
||||
# Only add if enabled AND not front view
|
||||
if auto_facing and horizontal_angle != "Front View (0°)":
|
||||
if language in ["Chinese (Best for dx8152 LoRAs)", "Hybrid (Chinese + English)"]:
|
||||
prompt_parts.append(f"面对{subject}") # "Facing {subject}"
|
||||
else:
|
||||
prompt_parts.append(f"Facing {subject} directly")
|
||||
```
|
||||
|
||||
### Behavior
|
||||
- **Active**: When `auto_facing=True` AND `horizontal_angle != "Front View (0°)"`
|
||||
- **Inactive**: When `auto_facing=False` OR `horizontal_angle == "Front View (0°)"` (redundant)
|
||||
- **Language Support**: Full Chinese/English/Hybrid support
|
||||
|
||||

|
||||
|
||||
## 2. Parameter Order Bug Fix
|
||||
|
||||
### Problem
|
||||
User reported: "i saw it is not working , the auto facing option is not working check it"
|
||||
|
||||
### Root Cause
|
||||
Parameter order mismatch between INPUT_TYPES definition and function signature.
|
||||
|
||||
ComfyUI passes parameters **positionally** based on INPUT_TYPES order. The function signature had parameters in wrong positions.
|
||||
|
||||
**Before**:
|
||||
- INPUT_TYPES position 5: `auto_facing`
|
||||
- Function signature position 8: `auto_facing`
|
||||
|
||||
### Fix
|
||||
Reordered function signature to match INPUT_TYPES exactly (Lines 591-601):
|
||||
```python
|
||||
def generate_cinematography_prompt(self, target_subject, shot_type, camera_angle,
|
||||
horizontal_angle, auto_facing, # CRITICAL: Must match INPUT_TYPES order
|
||||
depth_of_field, style_mood, prompt_language,
|
||||
...)
|
||||
```
|
||||
|
||||
**File**: `nodes/camera/cinematography_prompt_builder.py`
|
||||
|
||||
---
|
||||
|
||||
## 3. Chinese Distance Format Improvement
|
||||
|
||||
### Problem
|
||||
User showed prompt: "距离远距离" (distance far distance) - redundant and unclear
|
||||
|
||||
### Solution
|
||||
Changed `_get_distance_chinese()` function to return specific meter values instead of generic descriptions.
|
||||
|
||||
**Before**: "远距离" (far distance)
|
||||
**After**: "四米" (4 meters)
|
||||
|
||||
### Implementation (Lines 903-943)
|
||||
```python
|
||||
def _get_distance_chinese(self, distance):
|
||||
"""Convert distance to Chinese words with specific meter values"""
|
||||
chinese_numbers = {
|
||||
0: "零", 1: "一", 2: "两", 3: "三", 4: "四",
|
||||
5: "五", 6: "六", 7: "七", 8: "八", 9: "九",
|
||||
10: "十", 15: "十五", 20: "二十"
|
||||
}
|
||||
|
||||
if distance == int(distance):
|
||||
dist_int = int(distance)
|
||||
if dist_int in chinese_numbers:
|
||||
return f"{chinese_numbers[dist_int]}米"
|
||||
else:
|
||||
return f"{dist_int}米"
|
||||
# ... handles half meters and decimals
|
||||
```
|
||||
|
||||
**File**: `nodes/camera/cinematography_prompt_builder.py`
|
||||
|
||||

|
||||
|
||||
## 4. GRAG Nodes Fixed for ComfyUI Update
|
||||
|
||||
### Problem
|
||||
User reported: "there is an update for comfyui and t broken my GRAG nodes"
|
||||
|
||||
Error: `RuntimeError: The size of tensor a (8430) must match the size of tensor b (24)`
|
||||
|
||||
### Root Cause
|
||||
ComfyUI commit `4cd881866bad0cde70273cc123d725693c1f2759` changed:
|
||||
- Tensor format: **BSHD → BHND** (Batch, Heads, Sequence, Dim)
|
||||
- RoPE function: `apply_rotary_emb` → `apply_rope1`
|
||||
- Import location: `comfy.ldm.qwen_image.model` → `comfy.ldm.flux.math`
|
||||
|
||||
### Solution Applied
|
||||
|
||||
**File**: `nodes/sampling/archai3d_grag_sampler.py`
|
||||
|
||||
#### 1. QKV Projection Format (Lines 187-195)
|
||||
**Before**:
|
||||
```python
|
||||
img_query = attn_module.to_q(hidden_states).unflatten(-1, (attn_module.heads, -1))
|
||||
```
|
||||
|
||||
**After**:
|
||||
```python
|
||||
img_query = attn_module.to_q(hidden_states).view(batch_size, seq_img, attn_module.heads, -1).transpose(1, 2).contiguous()
|
||||
```
|
||||
|
||||
Changes to BHND format: `[B, H, N, D]`
|
||||
|
||||
#### 2. Concatenation Dimension (Lines 203-206)
|
||||
**Before**: `dim=1` (sequence in BSHD)
|
||||
**After**: `dim=2` (sequence in BHND)
|
||||
|
||||
```python
|
||||
joint_query = torch.cat([txt_query, img_query], dim=2)
|
||||
```
|
||||
|
||||
#### 3. RoPE Function Update (Lines 208-211)
|
||||
**Before**:
|
||||
```python
|
||||
from comfy.ldm.qwen_image.model import apply_rotary_emb
|
||||
joint_query = apply_rotary_emb(joint_query, image_rotary_emb)
|
||||
```
|
||||
|
||||
**After**:
|
||||
```python
|
||||
from comfy.ldm.flux.math import apply_rope1
|
||||
joint_query = apply_rope1(joint_query, image_rotary_emb)
|
||||
```
|
||||
|
||||
#### 4. GRAG Processing Format Conversion (Lines 216-232)
|
||||
```python
|
||||
# Convert BHND to BSHD format for GRAG, then flatten
|
||||
# BHND: [B, H, S, D] -> BSHD: [B, S, H, D] -> [B, S, H*D]
|
||||
joint_key_for_grag = joint_key.transpose(1, 2).contiguous() # BHND -> BSHD
|
||||
joint_key_flat = joint_key_for_grag.flatten(start_dim=2) # [B, S, H*D]
|
||||
|
||||
# Apply GRAG reweighting
|
||||
joint_key_flat = apply_grag_to_keys(...)
|
||||
|
||||
# Unflatten back to BSHD then transpose back to BHND
|
||||
joint_key_for_grag = joint_key_flat.unflatten(-1, (attn_module.heads, -1)) # [B, S, H, D]
|
||||
joint_key = joint_key_for_grag.transpose(1, 2).contiguous() # BSHD -> BHND
|
||||
```
|
||||
|
||||
#### 5. Attention Call with skip_reshape (Lines 241-252)
|
||||
**Key Insight**: With `skip_reshape=True` and default `skip_output_reshape=False`:
|
||||
- **Input**: BHND format
|
||||
- **Output**: BSD format (not BHND!)
|
||||
|
||||
```python
|
||||
# Pass tensors in BHND format with skip_reshape=True (new Qwen format)
|
||||
# Output will be BSD format (batch, seq, heads*dim) due to default skip_output_reshape=False
|
||||
joint_hidden_states = optimized_attention_masked(
|
||||
joint_query, joint_key, joint_value, attn_module.heads,
|
||||
attention_mask, transformer_options=transformer_options,
|
||||
skip_reshape=True # Input is BHND, output is BSD (due to default reshape)
|
||||
)
|
||||
|
||||
# Split streams - output is already in BSD format, no transpose needed
|
||||
txt_attn_output = joint_hidden_states[:, :seq_txt, :]
|
||||
img_attn_output = joint_hidden_states[:, seq_txt:, :]
|
||||
```
|
||||
|
||||
**Critical Fix**: Removed incorrect transpose that was treating output as BHND when it's actually BSD.
|
||||
|
||||
### Testing
|
||||
User confirmed: "ok GRAG is working"

# System Prompt Addition - Cinematography Prompt Builder
|
||||
|
||||
## Summary
|
||||
|
||||
Added dynamic system prompt functionality to the Cinematography Prompt Builder node to match the pattern used by all other camera nodes (Object Focus Camera v7/v6/v5, Scene Photographer).
|
||||
|
||||
---
|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Updated RETURN_TYPES (Line 287-288)
|
||||
|
||||
**Before:**
|
||||
```python
|
||||
RETURN_TYPES = ("STRING", "STRING", "STRING")
|
||||
RETURN_NAMES = ("simple_prompt", "professional_prompt", "description")
|
||||
```
|
||||
|
||||
**After:**
|
||||
```python
|
||||
RETURN_TYPES = ("STRING", "STRING", "STRING", "STRING")
|
||||
RETURN_NAMES = ("simple_prompt", "professional_prompt", "system_prompt", "description")
|
||||
```
|
||||
|
||||
**Impact:** Node now outputs 4 values instead of 3, adding system_prompt as the 3rd output
|
||||
|
||||
---
|
||||
|
||||
### 2. Added Dynamic System Prompt Method (Lines 390-441)
|
||||
|
||||
Created `_get_cinematography_system_prompt()` method with **3 intelligent variants**:
|
||||
|
||||
#### **Variant 1: Professional Mode** (Chinese + Presets)
|
||||
**Triggers when:**
|
||||
- Language is "Chinese (Best for dx8152 LoRAs)" OR "Hybrid (Chinese + English)"
|
||||
- AND material_preset OR quality_preset is selected
|
||||
|
||||
**System Prompt:**
|
||||
```
|
||||
"You are a professional cinematographer specializing in Qwen-VL camera control.
|
||||
Execute precise camera positioning using industry-standard shot sizes (ECU to EWS),
|
||||
camera angles (eye level to bird's eye), and lens characteristics (14mm to 200mm+).
|
||||
Maintain subject identity across viewpoint changes while allowing visual appearance
|
||||
to transform appropriately. Use distance-based positioning (e.g., '2.5 meters')
|
||||
rather than degree-based angular specifications for consistent results.
|
||||
Process Chinese cinematography terms (构图, 查看) with high accuracy for dx8152 LoRA compatibility."
|
||||
```
|
||||
|
||||
#### **Variant 2: Research-Validated Mode** (Advanced Technical)
|
||||
**Triggers when:**
|
||||
- `show_advanced_info = True`
|
||||
|
||||
**System Prompt:**
|
||||
```
|
||||
"You are an expert cinematographer trained in vision-language spatial reasoning.
|
||||
Follow the five-ingredient prompting framework: subject description, shot type and framing,
|
||||
angle and vantage point, focus and depth of field, style or mood.
|
||||
Process camera instructions through natural language spatial relationships—no pixel coordinates.
|
||||
Maintain geometric consistency by preserving subject identity (semantic pathway) while
|
||||
adapting visual appearance (reconstructive pathway) across viewpoint changes.
|
||||
Use M-RoPE position embeddings for 3D spatial understanding.
|
||||
Optimal guidance scale: 6-8 for camera control workflows.
|
||||
Distance-based positioning ('2.5 meters away') produces more reliable results than
|
||||
degree-based angular specifications ('45 degrees counterclockwise')."
|
||||
```
|
||||
|
||||
**Key Research Elements:**
|
||||
- M-RoPE position embeddings (from PDF page 1-2)
|
||||
- Dual-pathway architecture (semantic + reconstructive) (from PDF page 2-3)
|
||||
- Guidance scale 6-8 recommendation (from PDF page 4)
|
||||
- Distance-based vs degree-based positioning (from PDF page 5)
|
||||
|
||||
#### **Variant 3: Simple/Beginner Mode** (Default - Nanobanan)
|
||||
**Triggers when:**
|
||||
- Default mode (no special conditions)
|
||||
|
||||
**System Prompt:**
|
||||
```
|
||||
"You are a professional photographer following the five-ingredient framework:
|
||||
subject, shot type, angle, focus/depth of field, and style.
|
||||
Execute camera positioning using natural language descriptions of relative positions,
|
||||
distances (in meters), and viewpoints. Interpret cinematographic terminology accurately
|
||||
(extreme close-up, close-up, medium shot, wide shot, etc.) and maintain visual consistency
|
||||
across viewpoint changes. Preserve subject identity while allowing lighting, perspective,
|
||||
and visual details to change naturally with camera position."
|
||||
```
|
||||
|
||||
**Key Elements:**
|
||||
- Focus on Nanobanan's 5 ingredients
|
||||
- Natural language emphasis
|
||||
- Beginner-friendly terminology
|
||||

||||
|
||||
### 3. Updated generate_cinematography_prompt() Method (Lines 485-489)
|
||||
|
||||
**Added before return statement:**
|
||||
```python
|
||||
# Generate SYSTEM PROMPT (dynamic based on configuration)
|
||||
system_prompt = self._get_cinematography_system_prompt(
|
||||
prompt_language, show_advanced_info,
|
||||
material_detail_preset, photography_quality_preset
|
||||
)
|
||||
```
|
||||
|
||||
**Updated return statement (Line 497):**
|
||||
```python
|
||||
return (simple_prompt, professional_prompt, system_prompt, description)
|
||||
```
|
||||
|
||||
---
|
||||

# ArchAi3D GRAG-Aware Sampler Node
|
||||
#
|
||||
# OVERVIEW:
|
||||
# Custom sampler that injects GRAG (Group-Relative Attention Guidance) attention
|
||||
# patches into the sampling process for fine-grained image editing control.
|
||||
#
|
||||
# HOW IT WORKS:
|
||||
# 1. Extracts GRAG configuration from positive conditioning metadata
|
||||
# 2. Creates GRAG attention patch using the reweighting utilities
|
||||
# 3. Injects the patch via model transformer_options
|
||||
# 4. Calls standard ComfyUI sampler with GRAG-enhanced model
|
||||
# 5. CRITICAL: Restores original forward methods in finally block (v2.2.1 fix)
|
||||
#
|
||||
# USAGE:
|
||||
# [Any Encoder] → [GRAG Modifier] → [GRAG Sampler] → [Output]
|
||||
#
|
||||
# Or with GRAG Encoder:
|
||||
# [GRAG Encoder] → [GRAG Sampler] → [Output]
|
||||
#
|
||||
# BENEFITS:
|
||||
# - No ComfyUI core modifications
|
||||
# - Works with all existing encoders
|
||||
# - Update-safe implementation
|
||||
# - Clean on/off toggle
|
||||
# - Proper cleanup prevents global contamination (fixed in v2.2.1)
|
||||
#
|
||||
# CRITICAL FIX (v2.2.1):
|
||||
# Fixed global contamination bug where GRAG patches persisted across samplers.
|
||||
# Root cause: model.clone() creates shallow clone sharing diffusion_model references.
|
||||
# Solution: Store original forward methods and restore in finally block after sampling.
|
||||
# This ensures GRAG only affects intended generations and doesn't contaminate other samplers.
