Safelight Darkroom Timer

Darkroom-friendly timer, f-stop calculator, test strip runner, and saved print sessions for repeatable analog printing.

Safelight Darkroom Timer helps analog darkroom printers calculate exposure changes, run timed print workflows, and save the setup that worked.

Use the darkroom-friendly timer for Focus, Expose, and Process timing with large controls, red/amber/green display themes, optional haptic feedback, completion sound, and keep-screen-on behavior when enabled.

Turn one base exposure time into a stop-based table with the F-Stop Calculator. Use free 1/4 and 1/3 stop steps, send a result to the timer, or run a test strip one exposure at a time.

Save print sessions with base exposure, stop step, paper, filter grade, developer, and notes so you can repeat or adjust your best darkroom prints later. Search, edit, delete, repeat, and use saved sessions from the Sessions screen.

Use the Print Process Timer for expose, develop print, stop bath, fix, and optional wash steps. Manage darkroom metadata presets for paper, developer, and filter grades.

Safelight Pro unlocks unlimited saved sessions, advanced stop steps, Dodge & Burn planning, memory banks, run plans, and CSV/Text export and sharing.

Important: Safelight is a darkroom-friendly display and timing utility. It is not a flashlight, photo editor, AI app, lab ordering service, hardware enlarger controller, or guarantee that a phone screen is safe for every photographic paper or film. Always test your own paper and darkroom conditions.
