如何计算D O F

learn.whatIsHeading

A depth of field (DOF) calculator determines how much of a scene appears sharp in front of and behind the focus point. DOF depends on aperture (f-stop), focal length, sensor size, and subject distance — wider apertures and longer lenses create shallower depth of field.
