Practice question · Put in order
Arrange these shutter speeds from the longest exposure to the shortest.
- 1/15
- 1/60
- 1/125
- 1/500
- 1/30
- 1/250
Hints
- A larger denominator is a shorter time.
- Each step halves the time of the one before it.
Show the answer
- 1/15
- 1/30
- 1/60
- 1/125
- 1/250
- 1/500
Why
Each step is one stop, so the whole run from 1/15 to 1/500 is five stops, a factor of 32 in the time. The printed numbers are nominal: 1/15 is really about 1/16 and 1/125 about 1/128, and the powers of two are what the mechanism is actually doing.
