        "TEXTURE EQUALIZER TEST WORKFLOW\n\nPURPOSE:\n- Remove uneven lighting and shadows from textures\n- Based on Photoshop's High Pass + Linear Light technique\n- Perfect for cleaning albedo/diffuse and height maps\n\nHOW IT WORKS:\n1. Extracts average color from texture\n2. Applies High Pass filter to isolate details\n3. Blends using Linear Light mode to normalize lighting\n4. Optional: Preserves original color hue\n\nOUTPUTS:\n- image = Equalized result\n- average_color = Debug output showing extracted average tone\n\nPARAMETERS:\n- Radius: 50-150 typical (100 is default)\n  * Lower = preserves more gradients\n  * Higher = more aggressive flattening\n\n- Strength: 0.0-2.0\n  * 1.0 = full correction\n  * 0.5 = blend 50% with original\n  * 2.0 = exaggerated effect\n\n- Preserve Color: ON (recommended for albedo)\n  * Keeps original hue and saturation\n  * Only changes brightness/lighting\n\n- Method: overlay / soft_light / linear_light\n  * overlay = Photoshop standard (recommended)\n  * soft_light = Subtle, gentle correction\n  * linear_light = Strong, aggressive correction\n\nDEBUGGING:\nCheck console output for:\n- Average color values\n- High Pass range\n- Blend value range\n- Result before/after clamp\n\nIf output is too dark/bright:\n- Check average_color preview\n- Adjust radius (try 50-200)\n- Adjust strength (try 0.5-1.5)\n\nUSE CASES:\n✓ Photos with uneven lighting\n✓ Textures with shadows/highlights\n✓ Preparing textures for tiling\n✓ Cleaning scanned materials\n✓ Normalizing lighting variations\n\nREFERENCE:\nhttps://tolas.wordpress.com/2009/05/26/tutorial-how-to-equalize-textures-in-photoshop/"
