Peter A. Calvin - Professor - Collin College Photography

Depth of field (DOF) is simply what is sharp in the image. DOF is controlled by the

aperture (F stop). Small apertures (f16, 22) produce better DOF, wide apertures (f2, 1.4)

produce less DOF.  Set the aperture for the appropriate aperture, and then use the camera's exposure meter to determine the shutter speed for correct exposure. If your lens has it use the DOF scale.


GREAT DEPTH OF FIELD – (EVERYTHING IN FOCUS) Use small lens apertures (f 16,

22) to make photographs with everything in focus. Wide-angle lenses produce better

DOF. Use bright light or a tripod since small apertures admit little light and require longer exposures.



SHARP) Use wide apertures (f2, 2.8) to make images with only one part of the picture

sharp. Select either the background, foreground, or middle ground and make it the only

clearly focused part of the image. Telephoto lenses have less DOF than normal or WA

lenses at the same distance. Shoot in lower light or indoors since wide apertures admit lots of light.


Assignment:  you with turn in (as full resolution jpgs) 4 images, 2 great depth of field and 2 shallow depth of field. You will also print 2 (one example of each).  You are to use depth of field for a creative or narrative purpose and not treat this assignment as simply and exercise. Your images must be of 4 different situations.


4 files and 2 prints due Feb 21st
