Depth Of Field. The Depth of Field is a measure of how much ‘depth’ of an image will be in focus. An image with large depth of field will have much of.

DEPTH OF FIELD. DEPTH OF FIELD is the distance between the nearest and farthest objects in a scene that appears in sharp focus. The area in which objects.

Depth of Field

Parameters that Affect Depth of Field  format size or target size  aperture  focal length  distance from camera To REDUCE the depth of field:  use a larger format  use a wider aperture  use a longer focal length  reduce the focus distance (move closer)
