Shutter Speed

Shutter speed = the amount of time the shutter is open

Shutter = is a curtain in front of the camera sensor that stays closed until the camera fires

  • A fast Shutter speed is measured in fractions of a second e.g 1/100
  • The bigger the denominator (the number at the bottom) the faster the speed e.g 1/300 is faster than 1/200
  • Very slow shutter speeds are not measured in fractions, but just in seconds e.g 1 second, 10 seconds, 25 seconds etc.
  • If you want to freeze movement in a moving object (car, bird): use a fast shutter speed
  • If you want the image blurred in the moving object: use a slower shutter speed

 

IMG_0692.JPGThe above image is an example of a slow shutter speed, as the entire image is blurred. The shutter speed for this image  was low.

In this image, the shutter speed used was a high shutter speed, so the movement of the car was slowed down and the image was not blurred.
