Depth of Field

-Definiation-  Depth of field is the range of distance that appears acceptably sharp. It varies depending on camera type, aperture and focusing distance, although print size and viewing distance can also influence our perception of depth of field. Also, it is the distance between the nearest and farthest objects.    How to control depth of field- Larger apertures (smaller F-stop number) and closer focusing distances produce a shallower depth of field. The following test maintains the same focus distance, but changes the aperture setting.
