Exposure Calculator

The Easy Way to Calculate Exposure with or without ND filters on your camera

The most likely time to damage or break your neutral density filters is taking them on and off your camera. Rather than take your filters off to calculate your exposure time, leave them on and use this simple super fast technique!

Given an exposure (Aperture, Shutter speed, ISO), allows calculating equivalent exposures - set 2 new parameters (a combination of Aperture, Shutter and ISO) and the 3rd parameter is automatically calculated. It is also possible to add filters of up to 20 stops each to the calculations, handy for those long exposure photographs to blur water and take the moving clouds. The app also includes a timer for exposures of 30 seconds or longer.

Application Features:

- Aperture range from f/0.95 to f/128

- Shutter range from 1/64000s to 1d

- ISO range from ISO 16 to 204800

- ND filter 1 to 20 stops
