500 Rule Calculator is a useful tool for photographers who need to calculate proper exposure time for star photography and avoiding unnecessary light trails.

500 Rule Calculator(圖2)-速報App

The calculator uses the 500 Rule, and allows the user to select their camera's crop factor, so this app will work for photographers shooting full frame, general APS-C (Nikon, Pentax, etc.), or Canon APS-C. The app also allows the user to select from a wide variety of standard focal lengths, and get the time in seconds for the right shot.

The app also includes a countdown timer for use in star photography or any long exposure photography situation, ranging from zero seconds all the way up to 15 minute (900 second) exposure time.
