How it works
Calculate exposure value (EV) from aperture, shutter speed, and ISO.
Who it's for: Photographers comparing exposures and applying the exposure triangle.
EV = log₂(N²/t) where N is f-number and t is shutter time in seconds.
EV@ISO100 normalizes for ISO comparison.
Useful for matching exposures across settings.
How to use
- Enter f/, Shutter speed (seconds), and ISO.
- Read EV and EV@ISO100.
