Prompt

Apply a Color Channel Noise effect with independent red, green, and blue speckles scattered across the image. Make chromatic grain most visible in shadows and smooth surfaces, with occasional bright single-pixel flecks. Retain underlying contours and lighting without shifting entire color layers; keep the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗

Identify

Red-green-blue dots are a sign of sensor failure.

Principle

Independent noise is added for each color channel1.

Try it out

Separate luma and chroma noise2.

Classification

Calculated image processing result.
