GrainWorks: Film Sim & Bokeh

GrainWorks turns any photo into a fully editable computational photograph. Full 3D depth and bokeh, AI-powered color science, and film grain that reacts to light. Digital, with a true analog feel. Rendered entirely on your iPhone. Take a photo or choose one from your library—GrainWorks works with any image, building a complete depth map for any subject entirely on-device. Then physics comes into play: GrainWorks simulates every ray of light that reaches a pixel, then models the growth of each individual film grain to bring maximum realism to our film simulations. MAIN FEATURES - AI depth engine for high-quality depth reconstruction. Any photo—no depth data required. - True 3D bokeh—not an approximation made from stacked layers. We simulate how a real lens works. - Adjust the aperture and refocus after capture, with physically realistic focus falloff and aperture-blade-shaped highlights. - Scene-aware AI color science trained on thousands of real film scans, producing color that looks captured on film stock—not filtered. - The same physically simulated film grain used in M-Kamera—grain that grows and responds to exposure like real film, rather than sitting on top as a texture overlay. - Capture directly in the app or import any photo from your library. - Simple by design: a finished image in two taps, with full manual control whenever you want it. - Free for your first week, no purchase needed. Keep going with a monthly subscription, or a one-time purchase that's yours forever—both unlock everything above, on iPhone and Mac. PRIVATE BY DESIGN Depth estimation, bokeh rendering, color processing, and grain simulation all run on your iPhone using Metal and Core ML. GrainWorks never uploads or stores your photos anywhere. Made in Germany, with love for film and light. Requires iPhone 11 or later.
