HDR Effects (SuperBeasts.AI)

The HDR Effects is an image processing application that enhances the dynamic range and visual appeal of input images. It provides a set of adjustable parameters to fine-tune the HDR effect according to user preferences.

Features

• Adjusts the intensity of shadows, highlights, and overall HDR effect
• Applies gamma correction to control the overall brightness and contrast
• Enhances contrast and color saturation for more vibrant results
• Preserves color accuracy by processing the image in the LAB color space
• Utilizes luminance-based masks for targeted adjustments
• Blends the adjusted luminance with the original luminance for a balanced effect

Examples

Parameter details

The application provides the following adjustable parameters:

• hdr_intensity (default: 0.5, range: 0.0 to 5.0, step: 0.01):

  • Controls the overall intensity of the HDR effect
  • Higher values result in a more pronounced HDR effect

• shadow_intensity (default: 0.25, range: 0.0 to 1.0, step: 0.01):

  • Adjusts the intensity of shadows in the image
  • Higher values darken the shadows and increase contrast

• highlight_intensity (default: 0.75, range: 0.0 to 1.0, step: 0.01):

  • Adjusts the intensity of highlights in the image
  • Higher values brighten the highlights and increase contrast

• gamma_intensity (default: 0.25, range: 0.0 to 1.0, step: 0.01):

  • Controls the gamma correction applied to the image
  • Higher values increase the overall brightness and contrast

• contrast (default: 0.1, range: 0.0 to 1.0, step: 0.01):

  • Enhances the contrast of the image
  • Higher values result in more pronounced contrast

• enhance_color (default: 0.25, range: 0.0 to 1.0, step: 0.01):

  • Enhances the color saturation of the image
  • Higher values result in more vibrant colors
