What is a shutter speed?

§  shutter speed is the time for which the shutter is held open during the taking of a photograph to allow light to reach the film (on analog cameras) or image sensor (on digital cameras)

Regulates Light

§  In combination with variation of the lens aperture, the shutter speed regulates how much light the camera will record.

Page 4: Session 5 Shutter Speed (Basic Photography Class)

Shutter Speed & Aperture §  For a given exposure, a

fast shutter speed demands a larger aperture or more light to avoid under-exposure, just as a slow shutter speed is offset by a very small aperture to avoid over-exposure.

§  Long shutter speeds are often used in low light conditions, such as at night.

Freeze Action vs. Capture Motion

§  Two main issues:

§  Freeze the subject or the camera movement, or both;

§  Capture the subject’s motion, or camera shake, or both.

Speed Difference §  Shot at 1/15th of a

second using a tripod (see how the water makes long soft streaks)

§  Shot at 1/250th (even at this slow speed already it freezes the drops in the air)

Freezing Movement

§  High shutter speeds 'freeze' the subject’s movement as the subject has little time to move during the exposure.

Panning/ Slow Shutter Speed

Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects.

Page 16: Session 5 Shutter Speed (Basic Photography Class)

Camera Shake

§  Slow shutter speed can result in 'camera shake', caused by the photographer’s inability to hold the camera still.

§  Generally, shooting at less than 1/60th of a second may result in camera shake. To avoid this, a tripod can be used.

Handheld Rule and Blur

To avoid motion blurring, the shutter speed (in sec. ) should equal the reciprocal of the chosen focal length (in mm), i.e. 1/60sec for 60mm.
