Depth of Field

Students! For your DEPTH of FIELD assignment you must take a series of three photos. Each photo should be of the exact same scene, but with different depths of field. Use the same ISO if possible and the same shutter speed. That way the only two settings you are changing are the aperture and the focal length (lens length).
DO NOT USE A FLASH. Do use a tripod (or any stable place to sit your camera so it doesn't shake). Use your timer so you minimize blur.

Remember you have three decisions in regard to changing your depth of field:
1. Aperture size, 2. Focal Length, 3. Distance from lens to subject.

The first photo should have a shallow (small) depth of field, set your aperture so that it is in the F2.8 range (that is a large hole). Then, lengthen (or zoom-out ) your lens to maximize you focal length. Lastly, move close to your subject--within a few feet) I suggest you take a portrait. Focus on the person's eyes. Remember the Rule of Thirds! If you can't get your camera to F2.8, try to lower your ISO to the lowest setting and set your shutter speed so that it's faster.

The second photo should have a larger depth of field. Frame the shot just like the first one, but change your aperture to F8 or smaller (remember the F-numbers get bigger as the hole gets smaller, so try F11,F16, F22, F32 . Ideally the smaller the hole the greater depth of field.) If you can't get the camera to change the aperture setting, then shorten your focal length (lens length). Finally, if you still need to make your aperture smaller, increase your ISO.

The third photo should be somewhere in between. So, adjust your aperture in between what it was for the first and second photos.

Good Luck!
