About

Silver Lab

Read full description

Developing film should feel like a craft, not a calculation. Silver Lab is a darkroom timer built for film photographers who want to focus on the process and not the math. Select your film stock and developer, dial in your temperature and push/pull, and Silver Lab handles the rest. Development times are pulled from an extensive B&W film chart and automatically adjusted for temperature compensation and push/pull processing. For C-41 color negative, the full standardized process is built in and ready to go. When the timer starts, Silver Lab guides you through every stage โ€” agitation cycles, stop bath, fixer, and optional Permawash and Photo-Flo steps. The animated agitation timer tells you exactly when to agitate and when to let the film sit, so you can put the phone down between cycles and not think about it. Features - Automatic development time calculation across a large library of B&W film stocks and developers - Temperature compensation and push/pull adjustment - Configurable agitation timing โ€” set your own initial agitation, rest interval, and cycle duration, independently for Developer and Fixer - Optional Permawash and Photo-Flo steps - C-41 color negative process with push/pull support - Screen stays on throughout development - Live Activity functionality for longer developments - No accounts. No ads. No data collection. Everything runs locally on your device.
