3.7 + 0.6 F = 3.7 x 0.6 = 0.72 m 3.7 – 0.6 This gives a depth of field of 0.2 m, which is 5x greater than the 35mm camera delivers with the same effective lens aperture and subject distance. This is ...

The depth of field in an image is the distance between the parts that appear in focus. When there's a big distance between the things that look crisp and sharp, it's known as a wide or deep depth ...

Control depth of field after the fact. One of the wonders of modern engineering is a camera known as Lytro—it uses a sophisticated array of sensors to capture sharp focus everywhere in the scene ...
