Aperture and Shutter Speed

Definitions of Shutter Speed Shutter speeds are measured in seconds and fractions of a second and so the doubling and halving is fairly self-evident. One quarter second is half as long as one-half second but is twice as long as one-eighth. One second is twice as long as half a second and half as long as 2 seconds. It's pretty easy, and this works through the whole sequence of shutter speeds. On most cameras, the shutter speed sequence looks like this: 8 seconds 4 seconds 2 seconds 1 second 1/2 second 1/4 1/8 1/15 1/30 1/60 1/125 1/250 1/500 1/1000 Each of these settings is clearly half/double the length of time of its immediate neighbors (OK, I know, 1/15th isn't exactly half the time of 1/8th and 1/125th isn't exactly half the time of 1/60th, but it's close).
