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)).

To get the EV difference between two exposures I like to use use This Tool. Maybe I'll integrate something like this on this page in the future.
