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.
When the shutter speed is slower than or equals to one second, you will see something like 1â³ or 5â³ (the â sign indicates a full second). If you still cannot find the shutter speed, set your camera to âAperture Priorityâ mode, then look into the viewfinder and point at a really dark area. Remember the numbers in the display, then switch to a very bright area and see what number changes. The number that changes is your shutter speed.
