Session 5 Shutter Speed (Basic Photography Class)

  1. 1. SPEED MATTERS Basic Photography Class Mass Communication Department Ateneo de Davao University Bong S. Eliab
  2. 2. 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)
  3. 3. Regulates Light §  In combination with variation of the lens aperture, the shutter speed regulates how much light the camera will record.
  4. 4. Shutter Speed & Aperture §  For a given exposure, a fast shutter speed demands a larger aperture or more light to avoid underexposure, 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.

  11. 11. 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.
  12. 12. 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)
  13. 13. Freezing Movement §  High shutter speeds 'freeze' the subject’s movement as the subject has little time to move during the exposure. Blue Eagle Gym © Circa 1992

  15. 15. Panning/ Slow Shutter Speed Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects.
  16. 16. 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.
  17. 17. 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.
