Exposure Calculator

An application to calculate exposures by modifying shutter speed, aperture and ISO inputs based on an initial test exposure. This is not a light meter.

Given test exposure settings this application will calculate the final required shutter/aperture/ISO if you plan to deviate from any of the test settings.

This application is particularly useful for calculating those long star trail exposures or to calculate the required settings when using ND filters! Simply enter the number of stops the ND filter accounts for using the expoure compensation slider.
