Camera

Shutter Speed

Exposure time - length of time when shutter is open and exposed to light.

  • 1/4000 will freeze fast movement
  • 1/250 portraits, will freeze walking people
  • 1/150 general wildlife
  • 1/125 general landscapes

Aperature

Opening in camera lens that is able to limit the amount of light passing through the lens and hitting the camera sensor.

  • f-stop = aperature size; small f-stop = large aperature
  • f/1.4 very large, bright, small depth of field, nothing in focus
  • f/22 very small, dark, large depth of field, everything in focus
  • For blurry background, use low f-stop

ISO Speed

How quickly the camera reacts to light and records an image.

  • Low speed works great with lots of light
  • High speed works better when dull or dark
  • Higher the ISO, the noisier the photos. Generally keep low ISO (100-400)

Recipes

Portraits

  1. Shutter Speed 1/250 to freeze walking people
  2. Aperature 2.8 to blur background
  3. ISO 100-400 to reduce noise for bright scenes
  4. Focus mode - autofocus single point
  5. Drive mode - single shot

Other info

  • Shutter Speed at least 1/200th handheld or 1/15th on tripod (faster when photographing kids)
  • Aperature f/2 to f/4 for single subject, f/5.6 to f/8 for groups
  • ISO 800 if dark scene

Backlit Subjects

  1. Shutter Speed: 1/100 to 1/640
  2. Aperature: f/2.8 to f/5.6
  3. ISO: 100-200 (lower bc of strong light)

Other info

  • Combine wider apertures (from F/1.8 to F/5.6) with fast shutter speeds to get a significantly overexposed image (if you donโ€™t want to create silhouettes) and a very sharp figure.
  • Use the exposure dial for a better creational effect. By overexposing a little (2/3 of a stop to start), it will darken the subject, giving your subject more detail. By underexposing, a silhouette will be created, which works great in many cases.
  • Use a hood to prevent annoying flares, depends on the sun's position
