DoF Calculator

Depth of field (DoF) is the distance range in a photo that appears acceptably sharp. A shallow DoF blurs the background, while a deep DoF keeps everything in focus.

A wider aperture (lower f-number like f/1.8) creates shallower depth of field. A narrower aperture (higher f-number like f/16) creates deeper depth of field.

The hyperfocal distance is the focus distance that gives maximum depth of field. When focused at this distance, everything from half that distance to infinity is acceptably sharp.
