Visualize what's in focus based on your camera settings
Depth of field determines how much of your image appears sharp. It varies based on aperture, focal length, subject distance, and sensor size.

Wider aperture (f/1.4) = shallower DOF. Narrower (f/16) = deeper DOF.
Longer lenses compress perspective and reduce DOF at the same focus distance.
Closer subjects have shallower DOF. Background blur increases dramatically.
Sensor size also matters: smaller sensors have deeper DOF at equivalent settings because they require shorter focal lengths for the same field of view.
