"Depth of Field" The Purpose of this assignment is to see how your aperture setting determines the "depth of field" in your images. Use 100 speed black and white film. Shoot in early morning or later in the afternoon, or shoot in open shade or indoors with a tripod. Use at least a 50mm lens or greater (no wide angle lenses). Use manual focus on your camera. Shoot a subject that is still, not something in motion. Pick a subject that is no more than 5 feet away from you and has a view of some distance behind it. Focus on your subject for all exposures. Take each of your exposures from the same spot. If you have a tripod, use it. Shoot the first exposures with a wide aperture like f2, then go to f2.8, f4, and f5.6. (Change your shutter speed accordingly). Then shoot a series of shots from the same spot with a smaller aperture such as f11, f16, f22, f32, f45. (change shutter speeds for each exposure accordingly). Write down what you’re doing at the time you do it! Remember: Each time you change your f-stop (aperture) you must change your shutter speed accordingly (think about the exposure assignment, use your light meter), or put your camera on aperture priority (where you select the aperture and the camera selects the shutter speed). Turn In: In the end two 8 x 10’s will be required, along with your contact sheet. In the first print you will show a very shallow depth of field, and in the other you will show great depth of field. Be sure to write which aperture and shutter speed you used for your final prints when you hand them in. These prints will need to be mounted to share with the class on the due date.
