Frequently Asked Questions
Depth of field (DOF) is the distance between the nearest and farthest objects that appear acceptably sharp in a photograph. It depends on aperture, focal length, distance to subject, and sensor size.
A smaller f-number (wider aperture) reduces DOF, creating more background blur. A larger f-number (narrower aperture) increases DOF, keeping more of the scene in focus.
The circle of confusion (CoC) is the maximum blur spot size that still appears sharp to the human eye. It varies by sensor size; common values are 0.029mm for full-frame and 0.018mm for APS-C.
