Let say that we have the following values, as an example:
Shutter speed: 1/40
Aperture: 2
ISO: 1000
How can I get the EV number for this exposure, extract (or add) an EV value (0.33, 0.66 etc.) and calculate back the new shutter speed (or ISO) value?
In fact I want to calculate how the Exposure Compensation will affect my values.
