Simple Photography Exposure Time Calculator

The Easy Way to Calculate Exposure times with your 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/1.0 to f/32;

- Shutter range from 1/8000 to 30s;

- ISO range from ISO 100 to ISO 102400;

- ND filter up to 20 stops;

- ND filter modes: stop | ND number;

- Timer for exposures of 30s or longer with alarm;
