Transcript

  • 1.  “The total amount of light allowed to fall on the photographic medium during the process of taking a photograph” More light = Brighter that area Color Sun vs Moon over beach
  • 2.  Controlling exposure We control how much light is let in  ISO  Shutter  Aperture
  • 3.  Brightness is measured in Exposure Value “EV” or f-stops Step up – doubling Step down- halving What you see may not be what you get
  • 4.  Put camera on  Back in MANUAL MANUAL mode mode  Find controls to adjust  Same scenes as the 3 exposure points before, adjust up and Set camera to AUTO down a few f-stops and note the difference  find various lighting situations and look  Purposely over or through viewfinder and under expose for artistic hold down the shutter experiment half way to see what the camera has set
  • 5.  “an opening”  f ratio sequence in Can be adjusted (open stops or close) to control light  1 let in  1.4  Iris and Pupil  2 f ratio  2.8  f2.8  4  f22  5.6  8  11  16  22  32
  • 6.  Depth of Field  Region of photo that is in focus Larger the Aperture (small f/#) Smaller the Aperture (large f/#)
  • 7. Wide Depth of Field = Large f/#
  • 8. Narrow Depth of Field = Large f/#
  • 9.  Find interesting  Find a small object things that are at against a background many distances from  Adjust aperture to you. isolate the subject  Photography with from everything else different apertures  Find a house or and keeping photo landscape and adjust with correct exposure accordingly to have the whole photo in focus
  • 10.  Fast  Freeze motion in time Slow  Show motion Longer shutter  Ex. Make moving water look fluffy Long exposure at night  Can capture image in dim lighting
  • 11.  Shutter- Fast or Slow? Aperture- Big opening or little? Point of view? (worms eye, normal, birds eye) Composition (principle/elements of art) Rule of Thirds? What does the photo say to you? How does it make you feel?
