A Short Course in Photography: Chapters 1&2

In these entries relating to chapters from the photography book, I will write down things I find interesting, important to remember or confusing from the reading.

Chapter 1: camera


  • ISO= film speed, everytime you use a different kind of film you must set your camera to the correct film speed. Film canisters have DX codes which the camera reads to automatically know the film speed.
  • overexposed: too light
  • underexposed: too dark
  • SLR: single lens reflex, popular among photojournalists and fashion photographers
  • the faster the shutter speed, the sharper the moving object will appear
  • the smaller the aperture, the more of the picture that will be sharp
  • the longer the focal length, the larger objects will appear
  • you can set the camera to shutter or aperture priority to have the camera automatically change only the one
  • shutter speed: affects light and motion
    • slower: more light enters; more motion blur
    • faster: less light enters; less chance of motion blurring
  • aperture: affects light and depth of field
    • smaller: less light enters; more depth of field
    • bigger: more light enters; less depth of field

Chapter 2: Lens

  • a lens is not needed for a camera to work
  • main function is to project a sharp, undistorted image onto the light sensitive surface
  • lens focal length: dictates how much of a scene you can take in 
    • smaller the focal length, the more you get in a picture
    • longer allows you to zoom on things
    • med-long is good for portraits
    • short lenses can create interesting perspectives by making objects in the foreground larger
  • macro lens: used for close up photography
  • fisheye lens: distort image, lots of depth of field
  • sharp focus attracts the eye
  • lower aperture increases depth of field and more of the photograph will be in focus
  • shorter focal length increases depth of field
  • moving away from your subject increases depth of field
  • photographs can do a lot to determine the perspective and impression of subjects 
  • Close ups
    • depth of field is shallow
    • increase exposures
    • use a tripod
  • filters:
    • in black and white photography, blue tends to be faded and less sharp
    • filters lighten one color and darken all others
    • polarization helps when photographing around glass, water or any reflective surfaces but tend to work better at specific angles
