Abstract
A camera having a depth of field which can be modified to produce desired photographic effects. The camera determines the depth of field for a subject when the subject is focused upon. A modification to the depth of field is determined based upon the distance to the subject, and the depth of field is modified to produce the desired photographic effect. In one embodiment, the depth of field is reduced, while, in another embodiment, the depth of field is shifted to place the subject slightly out of focus and to alter the focus of the background.
