Depth of Focus

Depth of focus refers to the range within which an image remains acceptably sharp in a camera or optical system. When capturing a photo, even if the subject is slightly out of the ideal focus, it can still appear clear if it falls within this depth. A wider depth of focus means more of the scene stays in sharp detail, which is often desirable in landscapes. Conversely, a shallow depth can create a blurred background, isolating the subject. This concept is crucial in photography, cinematography, and optics, influencing how we perceive visual clarity in images.
