StochasticGrain
Read full descriptionHide full description
Unlike simple noise overlays, this app uses a physics-based approach where grain density responds to image brightness, just like analog film. Shadows show more grain, highlights stay cleaner. The result feels organic rather than digital. Built on academic research by Newson, Delon, and Galerne (2017) modeling stochastic film grain through Boolean models, with real-time optimizations informed by Zhang et al.'s 2023 SIGGRAPH work. These papers describe how actual silver halide crystals distribute in photographic emulsion. Exposure-dependent grain that responds to image luminance Real-time preview as you adjust Designed for film photography enthusiasts A passion project for anyone who appreciates the texture of analog photography.
