Aperture Settings

Modern aperture settings are marked in the following sequence: f1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45, and 64 etc. While the numbers may seem random, the fact is that each step is 1.414 times the previous step (1.414 is the square root of two).

Each f-stop represents a doubling or halving of the amount of light and comes as the square root of two - moving a light 1.4x further away halves the light, moving it 0.7x as far away doubles it.
