Understanding Lenses – Depth of Field

In a certain way, the opening question should be the other way around! There is a law of physics that governs the relationship between shutter speed and aperture (f-stop). Shutter speeds are pretty easy to understand: 1/60 second is one half as much time as 1/30. F-stops are a little different: f8 is one half the light of f5.6, which is half the light of f4! The point is, for any shutter speed/f-stop combo, one-half the exposure time with twice the light equals the same total amount of light given to the film – or pixels. 1/60 @ f4 = 1/30 @ f5.6 = 1/15 @ f 8.
