EV Calculator

I made this tool because when you search "ev calculator photography" every single result on the first page is flawed in some insane way. Most either round up TOO much, or don't let you enter certain values (like a 3 second exposure). I shouldn't have to fight with a calculator, this isn't a complex task. Here's the formula: EV = log₂((fstop² / seconds) * (100 / ISO)).

Try the EV Difference Calc to automatically get the difference between two exposures!
