Photo Glossary - 01 - Exposure

I run a photographic club in my office and part of that is a contribution to the internal weekly bulletin.  At the moment I am using it to put together a photo glossary, which I will mirror here.
This is the first entry, originally posted in February 2011.
Exposure is the amount of light that falls on your camera’s sensor.  It affects how bright or dark your image is.  In a well exposed photo you can make out all the colour and brightness details across the entire picture.  In an over-exposed photo lighter areas will be ‘blown out’ to white and in an under-exposed photo darker areas will be “crushed” to black.

Your camera has 3 methods of controlling the exposure of a photo: shutter speed, aperture and ISO setting.
