Exposure Compensation (for automated exposure modes)

  Cameras allow the user to conveniently adjust the exposure
  to over or under expose in increments of 1/3 stop up to plus
  or minus who stops.

  -2 -1  0 +1 +2   Over exposing by +1 stop might be just right
   |..|..|..|..|   photographing a bright scene as the one above.

  The snow scene above is typical of scenes that are lighter
  than 18 percent gray. Most of the important tones in the
  scene are at the lighter end of the gray scale. The overall
  "average" tone would be about one stop brighter than middle
  gray. For a good picture you have to increase the exposure
  by one stop (+1) to lighten it. If you didn't do this, the
  snow in the scene would appear too gray (bottom).

Using the Focus/Exposure Lock

  Many digital cameras are set to default to focus continually
  or have another focus mode that causes the camera to
  automatically select the main area that will be focused in a
  scene. These modes can be unreliable, resulting in poorly
  focused, soft looking images.

  For optimal results for the vast majority of scenes, switch
  to a single or center area focus mode and lock focus where
  you want it. Also make sure to set the diopter setting so
  that lines, boxes and information in the viewfinder is

  When pressing the shutter button half way, the camera comes
  alive--determining where to focus and determining what
  combinations shutter speed, aperture and sometimes ISO
  setting to give a proper exposure.

  Many times you want to focus on a subject that not in the
  center of the image.


  When the subject you want to expose (or focus) correctly is
  off-center, you can lock exposure (and focus) by pressing
  the shutter button halfway down and then, without releasing
  the shutter button, recompose the image.

Book Recommendations

John Berger
  About Looking
  Pantheon (1980)
  ISBN: 0679736557

  As a novelist, art critic, and cultural historian, John
  Berger is a writer of dazzling eloquence and arresting
  insight whose work amounts to a subtle, powerful critique of
  the canons of our civilization. In About Looking he explores
  our role as observers to reveal new layers of meaning in
  what we see. How do the animals we look at in zoos remind us
  of a relationship between man and beast all but lost in the
  twentieth century? What is it about looking at war
  photographs that doubles their already potent violence? How
  do the nudes of Rodin betray the threats to his authority
  and potency posed by clay and flesh? And how does solitude
  inform the art of Giacometti? In asking these and other
  questions, Berger quietly -- but fundamentally -- alters the
  vision of anyone who reads his work.
