Hyped on Depth

Understand what's in focus and why by investigating hyperfocal distances
written by: Patrick Gainer

The concept of hyperfocal distance (or hfd), is known and used by many photographers.When a camera is focused at the hfd, depth-of-field is maximized and everything from half that distance to infinity is acceptably sharp.The depth-of-field scale found on many lenses with a self-contained focusing barrel is easily used to set the lens at its hfd by aligning the infinity distance mark with the index for the f-stop in use. It is not so easy with view cameras, which may use any of several different lenses and different film formats.The darkness of the view screen at the apertures where hfd Read more »
