For example, if you're focused on somebody standing 10 feet in front of the camera, your depth of f By. Gemma . Furley. Depth of field. Depth of field is the range of the scene that stays sharp and focused. As we create small apertures the depth of field increases. As we set large apertures the depth of field decreases. .

There is always a zone either side of the focused point that is acceptably sharp. The size of this zone will depend on how far away the subject is; the focal length and aperture of the lens; the size of the final picture; and what you regard as 'acceptable'. . Module 5.

The aperture is the opening at the rear of the lens that determines how much light travels through the lens and falls on the image sensor. . The size of the aperture’s opening is measured in f-stops. How does the . aperture . affect exposure?. A WIDE/LARGE f/stop is a SMALLER number (f/2) = OPENS the aperture for MORE light. A SMALL f/stop is a LARGER number (f/22) = CLOSES the aperture for LESS light.. . Peter J. Munson, Ph.D.. Mathematical and Statistical Computing Laboratory. Division of Computational Bioscience.
