How would you change your depth of field?

Answer 1

If you are using a compact camera, digital or otherwise, the lens probably has no markings you can use. In this case, you will have to obtain a depth of field chart. If the camera has a depth of field scale on top of the lens barrel, you locate the f stop (the number) being used for the shot on both sides of the center dividing line and estimate the corresponding distances that line up with those numbers to get the depth of field as a range in feet or metres.

Describing this in words is virtually impossible, so the best I can suggest if you did not grasp the above, is to read up on it in your camera manual or Google it.

Answer 2

The size of the zone is determined by three key factors:-

the aperture of the lens, the focal length of the lens used, and the distance you are from the subject. Varying these three elements allows you almost complete control over the depth-of-field in a picture. So theoretically if you change any of these three factors then you change the field-of-depth

Answer 3

depends on the lens you have, also to maximize the amount of depth of field make sure your aperture is fully open, and also try to be as close to your subject as possible.
