Understanding Shutter Speed

Shutter speed is the amount of time the shutter is open. Slow shutter speed blurs the movement and takes more time which allows more light. Any movement when taking the picture appears blurred. Fast shutter speeds allow less light and freezes the movement. The movement in the picture appears clearly and looks frozen. When the shutter speed is slower the aperture is higher, and when the shutter speed is faster the aperture is lower so that it is balanced.
