• The aperture opening is measured in f-stops
• Higher numbers let in less light
• f/1.6 lets in more light than f/16

• To increase DOF– Use a wide angle setting– A high f stop setting (closing the aperture)– Long shots
• To decrease DOF– Use telephoto setting – A low f stop setting (opening the aperture)– Close ups

• Pull or Rack Focus– Changing the focal
point from on subject to another to draw the viewers attention.

• Focal Length and Angle of View– Using a telephoto setting will appear to
compress the distance between objects– A wide angle setting will give a more natural
representation of depth
