Wiktionary (0.00 / 0 votes) Rate this definition: shutter speed (Noun). The duration of time for which the shutter of a camera remains open when exposing photographic film or other photosensitive material to light for the purpose of recording an image.
Increasing ISO to a higher number allows you to shoot at higher shutter speeds. In low-light conditions, even a slight increase in shutter speed can help to get a sharp photograph. There is a huge difference between 1/25th and 1/50th of a second shutter speed, while there is only one stop of ISO increase in between.
