Combine Two Images with Light Mixing

****Blend two images together using additive color blending. Add pixel values from image 1 and image 2 to create a combined result. Can be used for many purposes: background replacement, combining extracted regions, merging different effects, or creative compositing. Perfect for flexible image combination workflows

What it does

Image Add blends two images together using additive color blending—adding their pixel values together. Each pixel's RGB values from both images are summed to create the output pixel (clamped at 255). Use it to combine two images in many ways: extracted foreground + background, two different crops, two different effects, or creative layering. Essential for flexible two-image compositing.

Problem it solves

• Combine two images – Add any two images of same size together
• Foreground + background – One common use: extracted object + new background
• Merge extracted regions – Combine two different extractions or crops
• Blend different effects – Combine image 1 with different processed version
• Two-part composition – Compose images with complementary properties
• Creative layering – Stack two images using additive blending
• Flexible combination – Many possible uses beyond single workflow
• Additive mixing – Brighten result by combining image values

Input/Output

<aside>

• Input: 2 images of same dimensions
  • Image 1: Any image
  • Image 2: Any image (same size as Image 1)
  • Dimensions: Both images must be same width × height

• Output: Single combined image
  • Format: Blended result image
  • Dimensions: Same as input images
  • Effect: Additive blend (Image 1 + Image 2 combined)
  • Result: Both images added together </aside>

How to Use

1. Prepare images → Ensure both images are same width × height
2. Load image → Upload Image 1 and Image 2 to Image Add tool
3. Run Flow
