Manual Exposure

Manual Exposure does the math for long exposures and night photography. Choose your equipment and settings, and the app gives you the exposure time. No tables or cheat sheets.

Calculators
• ND filters: exposure time with one or more ND filters.
• Handheld shutter speed: the slowest shutter speed you can use without blur.
• Multiple exposures: exposure compensation for multiple-exposure shots.
• Still stars: the longest exposure before stars start to trail.
• Star trails: exposure and number of frames for the trail length you want.
• Nightscapes: exposure for landscapes in moonlight.
• Moon: exposure for photographing the Moon itself.

Features
• Built-in timer. Start the countdown and close the app: you'll get a notification when time is up. Run several timers at once.
• Home Screen widget and Apple Watch app show the running timer.
• Equipment sets. Add cameras, lenses, filters and teleconverters from the catalog, and switch sets in any calculator.
• Specs for every item in your sets.
• Save your favorite calculators and reopen them with one tap.
• ND filter compensation and lens stabilization settings.
• Light and dark mode, support for larger text sizes.
