Caffenol

Caffenol is a darkroom simulation toy that recreates analog film development and printing. Load a photo, develop it into a negative in a simulated tank, then print it under a timed enlarger. Shape the light with hand-waving cut cards to dodge and burn your print.

Powered by WebGPU, it simulates actual film and paper chemistry. Each run produces unique, organic results with built-in chaos. The tool emphasizes experimentation with minimal constraints, letting you explore darkroom techniques interactively.
