Depth of field refers to the range of distances in front of and behind the subject that appear acceptably sharp in the image
Factors that affect depth of field include
- Aperture size - A wider aperture (smaller f-number) results in a shallower depth of field, while a narrower aperture (larger f-number) increases depth of field
- Focal length - Longer focal lengths produce a shallower depth of field compared to shorter focal lengths
- Distance to subject - As the distance to the subject increases, the depth of field also increases
