Focusing on a camera
AF (auto focus) is more typically used when taking photos as the camera will focus its self. MF (manual focus) is more effective when trying to get a specific light or focal point.
Aperture
the aperture setting controls the size of the lens opening that allows light into your camera. You can blur the foreground and background that bracket your subject (known as shallow depth of field) by opening up the aperture with a low f-stop number; alternatively, you can keep your photo sharp from the foreground through to the background (known as wide depth of field) by closing the aperture down with a high f-stop number.
Focal length
The focal length of a lens is the optical distance (mm) from the point where the light meets inside the lens to the camera’s sensor.
Depth of field
The photographer can change the settings on the camera in order to alter the amount of light entering the lens. This directly affects the depth of field of the subject being viewed
deep depth of field
medium depth of field
shallow depth of field
