“Great photography is about depth of feeling, not depth of field.”
— Peter Adams
As aperture changes in size, it alters the overall amount of light that reaches your camera sensor – and therefore the brightness of your image. A large aperture (a wide opening) will pass a lot of light, resulting in a brighter photograph. A small aperture does just the opposite, making a photo darker. In a dark environment – indoors, or at night – you will probably want to select a large aperture to capture as much light as possible. |
Lenses with longer focal lengths are slower (have smaller maximum apertures) than wide-angle lenses. Cameras use mechanical diaphragms to control how much light passes into the camera body and strikes the image sensor or film. That diaphragm works a lot like the irises in your eyes; it contracts or expands depending on how much light is needed. Aperture refers to the diameter of the opening.
