Safelight Darkroom Timer vs PaperDeveloper

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.

PaperDeveloper is a precise darkroom timer for the full wet process of photographic paper. Set your paper, chemistry, dilution, temperature and volumes. The app sets accurate times based on manufacturer data. The built-in timer guides you through every step — developer, stop bath, fixer, wash, and optional toning. Track multiple papers and test strips at once, and save quick presets. KEY FEATURES • Timing for the full B&W paper wet process • Papers, chemistry, dilutions and temperatures • Multiple runs at once (paper + test strip) • Presets for quick setup • Chemical capacity / yield tracking • Red UI for darkroom use • Works offline — no account, no cloud Currently the app includes manufacturer materials from FOMA. In a future version we will add materials from manufacturers such as Ilford and ADOX. Important: the red interface helps in the darkroom, but PaperDeveloper is not a certified safelight. Please keep that in mind. Enlarge — don’t scan!
