Store description excerpt
Grain is the essential toolkit for analog and film photographers. Every tool you need in the field and in the darkroom — in one clean, offline app. LIGHT METER Point your camera at any scene and get an instant exposure reading. Choose between Spot and Evaluative metering modes. Results display as EV value with matched aperture, shutter speed, and ISO combinations — ready to dial in. EXPOSURE CALCULATOR The Sunny 16 calculator gives you perfect exposure for any lighting condition — blazing sun, open shade, overcast, or candlelight. Enter your film speed and shutter speed and Grain gives you the aperture instantly. Built-in reciprocity correction handles long exposures so you never lose shadow detail again. FILM ROLL TRACKER Log every roll you shoot. Track film stock, camera body, ISO, shot count, date, and development status — from Loaded through Exposed to Developed. Attach photos of your negatives or contact sheets. Your complete shooting history, always in your pocket. DARKROOM TIMER Time every step of your development process. Set custom step durations, follow agitation cues, and switch to safelight mode to protect your prints while the timer keeps running in the background. DARKROOM CALCULATOR Mix developer, stop bath, and fixer solutions accurately. Choose your chemical, target volume, and dilution ratio — Grain tells you exactly how much concentrate and water to use. No subscriptions. No accounts. No cloud. All your data stays on your device. Grain. Shoot more. Develop better
