How to use this table

Find the row closest to your aperture (f-number) and read across to the exposure value (ev). For a value between two rows, the real figure sits between them — or enter your exact numbers in the Exposure Value Calculator for a precise answer.

Need a value that is not in the table? — the Exposure Value Calculator does it instantly, for free, with the formula and a worked example built in.
