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.

Whether you’ve just bought your first DSLR or you’re an avid photographer, evaluating your own photographs can prove a challenge.
