Shutter Timer & Shutter Speed Calculator

This app is useful for photographers wanting to know how much time is remaining while theyre capturing long exposure images. This timer counts down in seconds from 900 seconds (15 minutes), or any time between 0 and 15 minutes.

The calculator built into the app calculates adjusted shutter speeds based on a benchmark shutter speed and user selected f-stop compensation, say for using Neutral Density filters.

If youve ever been out taking photographs and set a long exposure, and wondered how much time you have left until the exposure will end, this is for you.

For example, if youve setup your camera and tripod and figured the correct shutter speed, but need to compensate for increased shutter speed due to Neutral Density filters or other changes, you may have struggled to perform the calculation. The formula isnt the easiest to remember, and certainly not easy to do on a standard calculator. This app does it for you.
