I’ve written a simple photography application for iOS called Photos Master that calculates Sunset and Sunrise times on a current date and at the given GPS location. The application also helps to determine the Hyperfocal Distance and Depth Of Field for any lens, its aperture, and camera’s sensor size (full frame, cropped etc.)

The app uses complicated astronomy algorithms to determine time of a sunset/sunrise. It does not need the Internet connection either. It’s all done via calculations based on the GPS location and current date. The app is completely free and available on Apple Store in 4 languages. If you’re interested in helping me translate it into more languages, send me an email and I’ll be happy to work with you. Currently it supports French, Polish, English, and simplified Chinese.

Over the last couple of years I’ve gotten lots of reviews and suggestions on how to further improve (or add more functionality to) the application. Everything is possible. I’m too busy right now to work on it, but if I find some spare time I’ll improve it, or add more features.

But, if you have some suggestions, don’t hesitate to contact me!

Most frequent requests:

  1. Calculate sunset/sunrise times for future dates.
  2. When calculating depth of field, allow decimal point.
  3. Add/calculate moonset/rise (useful when shooting Milky Way)
