  57. 57. Cropping a photo – Example 05 Digital Photography using Picasa 57
  58. 58. Aspect ratio Crop to either: Make the photo right for a certain sized frame, or Improve the picture composition and balance, or Both This specifies relative shape, not absolute size For example, “8 x 10” forces the crop so that one edge 25% (10/8) larger than other Manual does not constrain the shape Digital Photography using Picasa 58
  59. 59. Digital Photography using Picasa 59
  60. 60. What is Aspect ratio and why is it important You camera has a sensor of a certain size and with a specific number of pixels wide and high Conventional photos use a specific widths and heights Examples My camera Portrait frame Desktop photo Small Photo HD TV SD TV 3872 x 2592 10 x 8 7x5 6x4 16 x 9 4x3 Digital Photography using Picasa 1.49 x 1 1.25 x 1 1.40 x 1 1.50 x 1 1.77 x 1 1.33 x 1 60
  61. 61. Redeye Occurs when light is reflected back BTW on animals it is green It is worse in low light when subjects eyes are dilated How to handle Don’t use a flash Use redeye reduction flash (double flash to un-dilate) Move the flash away from lens (separate flash) Fix in software Digital Photography using Picasa 61
  62. 62. Fixing Redeye in software Double click on Example 06 Digital Photography using Picasa 62
  63. 63. ZOOM on a camera Optical zoom – uses camera optics to control telephoto and wide angle Digital zoom – camera takes a part of the picture and expands the picture by adding missing pixels (interpolating) Larry’s rule (and probably everyone else): NEVER use digital zoom. Instead use highest resolution and use computer software to expand picture. Digital Photography using Picasa 63

  69. 69. To Flash Flash if The subject is in the shadows There is not enough light to get a good exposure Digital Photography using Picasa 69
  70. 70. Or not to Flash Don’t flash if Subject is too far away, > 10 feet for most cameras (flash doesn’t help but the camera doesn’t know) In front of glass (all you will get is the flash flare) At an event or museum (if cameras are allowed) You CAN get a good photo without it Digital Photography using Picasa 70
