Exposure
A camera is nothing more than a light-tight box that holds film (electronic or traditional), a lens to focus the image and a shutter and aperture to control exposure. This definition is equally true of the most expensive Leica and the cheapest disposable.
Exposure is simply the control of the amount of light used to create an image. Exposure is made up of three elements;
- Shutter speed - the amount of time the hole in the camera is allowed to remain open
- Aperture - the size of the hole in the camera
- Film speed - the sensitivity of the film or sensor to light.
There are many correct exposures for a given situation; part of the technical art of photography is choosing the right exposure to capture a scene as you see it or wish to portray it.
- Aperture and F-Stops
- Shutter Speed
- ISO and Grain
- Latitude
