Exposure Calculator

Exposure Calculator app at a glance:

You don’t need to be Sherlock Holmes to guess what Quicosoft’s Exposure Calculator does, but just in case you missed a few lectures at detective school, this app is designed to calculate your image exposures.

The idea is you can set the ISO, shutter speed and aperture that you are using and from there you can calculate what the shutter speed would be if you added an ND filter. However, you can also reverse that to calculate what the exposure would be if you were to put on a lower-strength ND filter or take off an ND filter altogether. Under Current Exposure, the bit where you put all your current parameters, there’s a New Exposure option as well as Tracking Options. This allows users to tweak their ISO sensitivity setting or aperture to see what it would do to the shutter speed. Tracking Options simply resets it to the base parameters of the current exposure – effectively a reset mode.
