Depth of Field: (DOF) the portion of a photograph that appears acceptably sharp or in focus.

Two Major Variables:1. Aperture2. Focal Length

Example: deep or broad Depth of Field

Example: a narrow Depth of Field

Narrow Depth of Field

•Long Focal Length •Maximize Optical Zoom

focal length: 200 mm

Deep Depth of Field

•Short Focal Length •Wide angle lens

Focal length: 15 mm
