Aperture-Before light reaches film, it must pass through an opening called an "Aperture". The aperture is like a pupil. You can control the aperture by setting the "Aperture Opening", also known as an F-Stop.
Shutter-The shutter blocks all light from exposing the film UNTIL you press the button. Then it quickly opens and closes, giving the film a brief flash of light.
Exposure-is the amount of light allowed to fall on each area unit of a photographic medium during the process of taking a photograph. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region.
Depth of Field-is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.
F-stop-an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography.
focal length-a measure of how strongly the system converges or diverges light
