Photography Aperture & Aperture Priority Mode Aperture is the hole inside your camera lens.

Photography Aperture & Aperture Priority Mode

This hole, known as the diaphram is formed by a number of overlapping blades that adjust to control the size of the hole opening. Depending on the type of lens, the hole opening or what we will refer to as aperture can be adjusted manually on the lens (Manual Lenses) or automatically (Automatic Lenses) by your camera using buttons or dials (on the camera). When you do this adjustment, the aperture either increases or decreases which in turn controls how much light can pass through the lens and onto the digital sensor or film.

Aperture settings are expresssed in f-stops and are represented by numbers (i.e. f/2, f/5.6, f/11, etc). What Is A Fast Lens? — We Are SO Photo. The speed of a lens relates to its maximum aperture.
