Depth+of+Field+1

__Depth of Field__ Tory Depth of Field (DOF) is about how much and what part of a photograph is blurred. The DOF doesn't change from sharp to blurry suddenly, but is rather a transition. "Landscapes have great depth of field, while macro photographs tend to have very little depth of field because the subject is so close to the lens." (1)

When you use a smaller aperture (f/8, f/11, f/16, f/22) everything will be sharp, but when you use a larger aperture (f/2.8, f/2, f/1.4) the DOF is limited.

(1) DOF differs by three factors: shooting distance, focal length, and aperture. When one factor is changed and the other two remain the same, the depth of field changes drastically.

(4) "In photo A the lens was employed at f/16 and two mesh wires present themselves as dark bands across the frame. Photo B was taken at the lens full aperture of f/1.4. The mesh is now completely invisible, even though the wires are still there, right in front of the lens." (2) media type="youtube" key="Wv310dokodg" height="315" width="420"
