Understanding Shutter Speed Setting Options
As you adjust the settings for the shutter speed, you’ll probably find fast settings that begin at 1/2000 or 1/4000 and that may end at the slowest speeds of 1 or 2 seconds. The settings will nearly always be about half or double the previous setting, going from 1/30 to 1/60 to 1/125, and so on, although some cameras offer even more precise settings in between the standard shutter speed settings.
There will be times when shooting with shutter priority where you may want to use a relatively slow shutter speed. If you’re going to shoot at a slow shutter speed, anything 1/60th or slower, you will likely need a tripod, a remote shutter, or a shutter bulb to shoot photos. At the slow shutter speeds, even the act of pressing a shutter button could jostle the camera enough to cause a blurry photo. It’s also extremely difficult to hold a camera steady by hand when shooting at slow shutter speeds, meaning camera shake could cause a slightly blurry photo, unless you make use of a tripod.
