Understanding Shutter Speeds

Slow Shutter Speed

ISO: 1600   AP: f/4.5 Shutter Speed: 1/50

Fast Shutter Speed

ISO: 1600   AP: f/4.5   Shutter Speed: 1/800

Shutter speed is the amount of time that that the shutter of the camera is open. The smaller the shutter speed is, the more blurred the photo becomes. This is because the shutter is open for a longer time. Then if the shutter speed is larger, the photo looks like its frozen in time. This is because the shutter is open for a shorter time. The shutter speed is at the bottom right of the exposure triangle and it plays a big part in capturing a photo in the way you want (blurry or frozen).
