Types of shutters
Shutter controls exposure of the film to light by opening and closing at various speeds.
Focal-plane shutter is built into the camera body at the point directly in front of the film.
Types of shutters
Leaf shutters are located within the lens and consists of several small, overlapping spring-powered metal blades.
Aperture
Aperture also controls the exposure of the film to light.
The aperture fixes the size of the lens opening.
Larger aperture sizes allow more light through the lens.
Smaller aperture sizes allow less light in.
Measured in f-stops.

The lens sorts out various light rays, focuses them, and directs them to reproduce the subject accurately on film.
