Use of DOF (depth of field) button in your DSLR camera

Thursday, June 2, 2011

The DOF preview button in your DSLR camera helps you to check the DOF that will be in the final shot. The lens aperture closes to the predefined value (lets say to f8 for example). The viewfinder gets darker, as less light transfers through the lens. But that is not everything. The DOF you see in the viewfinder is the same as will be in the final photograph. The DOF preview is useful when composing. However, if you have a f2.8 lens and the camera set to shoot at f2.8, pressing the DOF preview button does nothing. As expected, becouse the lens is wide and will be used wide open.
