ExposureTool

This application allows to calculate the exposure starting from the time/aperture pair (or by EVs) taken by the camera or by an external meter. It is possible to add the attenuation of a filter.
The application is particularly useful when using ND filters that cause the extension of shutter speeds.
When the final exposure is computed, it is possible to choose digital or film media.
In case film is the choice (several types are managed) the reciprocity failure is automatically added.
There is also a timer that automatically set to the final shutter speed and beep at the end of the count.
