www.dombower.com DOF or Depth of Field is referring to how much of the image is in focus and nice and sharp. shallow (or narrow or short) Depth of field is when you have only a small region of the image in focus and the rest becomes a bit blurry) Deep (or great) depth of field is when you have lots of things in focus from objects in the forground to objects in the background. DOF is affected by 3 things (which each affect eachother) 1. Focal length of the lens (ie 30mm, 50mm, 105mm etc) 2. Aperture size (F 3. Distance from subject to camera and background If you have a subject you want to shoot that is 1meter away, and the background of that subject is 5 meters behind that, then to get a very shallow depth of field (ie have the background nice and blurry) you should have a big aperture (small F/number), or get closer to the subject, or use a longer focal length lens. If you want a deep depth of field you should either stand further away from the subject, have a smaller aperture (larger F/number) or a shorter focal length lens (ie going from a 50mm to a 20mm) hope that helps. copy right www.dombower.com
