  1. · Shutter Speed · Aperture · ISO basics There are

    really only three things that you need to learn to understand photography.
  2. ISO How sensitive your camera is to the light that

    managed to get through to the sensor. (Yes, it is the same ISO you are thinking about… )
  3. Zoom lens A zoom lens is a mechanical assembly of

    lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a prime lens.
  4. Prime lens A prime lens is a photographic lens whose

    focal length is fixed, as opposed to a zoom lens.
  5. Cheat sheet Exposure Aperture Aperture Shutter Shutter ISO ISO Try

    to keep your light meter at 0 Shallow depth of field Brighter Deep depth of field Darker Longer exposure Brighter Shorter exposure Darker Low, higher quality (smooth) Day High, lower quality (noisy) Night
