Still Life

These two photos show an example of deep and shallow depth of field. In this case, the difference is made mostly by subject to camera distance.

Deep Depth of Field: Created by subject to camera distance. It is deep depth of field because almost everything is in focus.
Focal length: 28 mm; Aperture: f/4.5; Shutter speed: 1/30 s.

Shallow Depth of Field: Created by subject to camera distance and focal length. It is shallow depth of field because the lavender in the bag is the only thing that is in focus.
Focal length: 55 mm; Aperture: f/5.6; Shutter speed: 1/10 s.
