In this photography lecture we’ll discuss camera shutter speeds. The shutter speed is one of the controls that determines the exact amount of exposure your film or image sensor receives.

Shutter speed controls the time of an exposure by controlling exactly how long the aperture remains open. The shutter speed also has other effects on your pictures which will be covered as well.

The following is a list of the full shutter speeds, starting with 1 second:

1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, etc.

Each of the above shutter speeds is 1/2 the amount of time as the previous speed.
