What is Depth Of Field (DOF)

The distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.

One fo the key elements of aperture is depth of field. All variables in photography have a give and take, and with your aperture as we gain light we also lose depth of field. But aperture is not the only variable the affects depth of field, so we will take a look at those other variables.

In this lesson you will see how DOF is controlled by two key elements F-stops and distance from camera to subject and we'll take look at a few other variables.
