Bayer CFA Mosaic (05 Video & Glitch) — Atlas of Visual Effects

Atlas demonstration: the free source photo and the computed Bayer CFA Mosaic. A scenic landscape captures a waterfall cascading through a lush, verdant forest. The zoom reveals a precise, alternating grid of red, green, and blue pixels that reconstructs the forest's greenery.Image: adrian aows · CC0 (via Wikimedia Commons), processed for the AtlasView source ↗

Prompt

Apply Bayer CFA Mosaic, converting the photograph into a fine, visibly resolved checkerboard of single-channel samples. Repeat two-by-two tiles containing two green sites, one red site, and one blue site, each varying in brightness with the source image. Avoid blended pixel colors. Keep the original subject and composition.

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

Identify

The image becomes a fine grid of red, green, and blue samples, with a repeating checkerboard texture.

Principle

The algorithm imitates a Bayer color filter array¹, repeating a two-by-two tile with two green sites, one red, and one blue. Each site retains one color channel² from the source image; the other two are set to zero for display.

Try it out

Zoom in to inspect the repeating tile and compare its appearance across bright and dark areas.
