Tip: A wider aperture (lower f-number) gives shallower depth of field. Longer focal lengths also reduce DoF at the same distance.

FAQ

What is depth of field?
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.
How does aperture affect DoF?
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.
What is hyperfocal distance?
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.
