What is Aperture?

Aperture is a device that controls the quantity of light that passes through the lens. It is an iris type mechanism, which shrinks or grows in order to let in less or more light.

The numbers you usually see on a lens are:

F: 3.5 4.5 5.6 8 11 16 22 32

Each number lets in two times less light than the previous one.

Small numbers represent a large aperture, big numbers - small aperture. Most digital cameras do not have this numbers written on their lenses, but they use aperture as part of their construction. It is also the way for you to select aperture priority shooting mode from your camera to control the depth of field.
