What is Depth of Field?
Depth of field (DoF) is the distance between the nearest and farthest objects in a photo that appear acceptably sharp. A shallow DoF isolates subjects with a blurry background; a deep DoF keeps everything in focus.
Factors Affecting DoF
Wider aperture (lower f-number) creates shallower DoF. Longer focal length compresses perspective and reduces DoF. Closer subject distance dramatically decreases DoF. Larger sensors produce shallower DoF at equivalent framing.
Hyperfocal Distance
The hyperfocal distance is the closest focusing distance at which infinity remains acceptably sharp. Focus at this distance to maximize depth of field—ideal for landscape photography where you want both foreground and background in focus.
