Exposure Calculator - Donate6.0.3 - Google Play

This is exactly the same app as the free one. If you haven't tried that one yet, please install it and take it for a spin. Afterwards, if you think it is worth 3 Euros, feel free to come back here and install this one.

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 1 to 3 ND filters of up to 30 stops each to the calculations, handy for those long exposure photographs to blur water and clouds.

The app also includes a timer for exposures of 4 seconds or longer.

Main features:
 • calculates Shutter, Aperture or ISO
 • aperture range from f1.0 to f360
 • shutter range from 480s to 1/16,000s
 • ISO range from ISO 0.4 to ISO 3.2M
 • ND filter up to 30 stops, in 1, 1/2 or 1/3 stop increments

Note: in the Shutter settings section there is a switch tor camera type. This switch simply selects how a small set of shutter speeds around 1 second are displayed, choose the one your camera adheres to. Exposure calculations work for all camera makes, this switch is simply for display purposes.
