How a camera works….

The Body

Lens Image quality is greatly affected by the quality of the lens.

There are many types of lenses, but most fit into two categories: fixed focal length or zoom

Most cameras contain lenses which are comprised of several "lens elements."

Types of lenses

Standard

Wide-angle

Telephoto

Zoom

Aperture

The aperture is a small set of blades, in the lens, that controls how much light will enter the camera.

Aperture sizes are measured in f/stops.

Shutter A shutter on a camera controls how long

light will enter.

Very short shutter speeds are used to freeze action (sporting events).

Very long shutter speeds are used to intentionally blur a action for artistic effect.

Shutter speed is one of the “three pillars of photography”.
