Depth of Field Table

Depth of Field Definition

Depth of field is the distance between the nearest and furthest parts of a subject that can be imaged with acceptably sharp detail at one focus setting of the lens.

Basic Photography, Seventh Edition, Michael Langford, 2000

Depth of field refers to the section of a photograph that appears to be in sharp focus.

John Shaw's Nature Photography Field Guide, John Shaw, 2000

When an object is in focus, everything from a certain distance in front of the object to a certain distance behind the object will also be in reasonably sharp focus. This distance from front to back that will be in reasonably sharp focus is called the depth of field.

Hyperfocal Distance Definition

The hyperfocal distance is the point you focus on when you want to maximize the amount of depth of field in a photograph.

Lonely Planet Landscape Photography: A Guide to Taking Better Pictures, Peter Eastway, 2005.

Hyperfocal distance is the point of focus at which subjects from half that distance to infinity are in focus.
