Shutter Speed

Shutter speed is the amount of times the cameras shutter is open in order to expose the light sensitive media. It is measured in fractions of a second, a faster shutter speed halves the amount of light allowed in the camera, a slower shutter speed doubles the amount of light allowed into the camera.

When setting the shutter speed on the DSLR, you choose the TV which means time value on the dial. The camera will then calculate the appropriate aperture for the correct exposure shown in the view finder.

There are 10 options for slow shutter speeds:

- 1/1000

- 1/500

- 1/250

- 1/125

- 1/60

- 1/30

- 1/15

- 1/8

- 1/4

- 1/2

All of them are in fractions of a second.

However, long shutter speeds are done in whole seconds:

- 1

- 2

- 4

- 8

- 16

- 32

- 60
