Depth of field quick guide
Depth of field (DOF) is primarily controlled by aperture size. Other factors also come into play such as the focal length of the lens.
To increase DOF
For distant subjects
Higher F-stop numbers (smaller apertures)
Shorter focal lengths (wide angle)
To decrease DOF
For close-ups
Lower F-stop numbers (larger apertures)
Longer focal lengths (zoomed in)
