Depth-of-field refers to the total area (foreground and background) which will appear in focus (sharp). The area of sharpness (depth-of-field) depends upon the distance the lens is focused at, the f/stop (or aperture) being used, and the focal length of the lens. The area that will appear sharp can be determined in three ways: 1. The Depth-of-Field[...]
