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 specify an ND filter of up to 30 stops, handy for those long exposure photographs to blur water and clouds.
The app also includes a timer for exposure of 4 seconds or longer.
Note: in the Shutter settings section there is a switch tor camera type (Canon/Nikon). 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.
