Aperture- is a hole or an opening through which lights travels. More specifically, the aperture of an optical system is the opening that determines the cone angle of a bundle of rays that come to a focus in the image plane.
Shutter- s a device that allows light to pass for a determined period of time, for the purpose of exposing
photographic film
or a light-sensitive electronic sensor to light to capture a permanent
image of a scene.
Exosure-is the amount of light allowed to fall on each area during the process of taking a photo. Exposure is measured in seconds, and can be computed from exposure value.
Depth of field- is the distance between the nearest and fartherst objects in a scene that appear acceptably sharp in an image.
