Exposure
The amount of light that exposes a frame is determined by the aperture and shutter
speed. The size of the aperture controls the amount of light allowed to reach the
film, while the shutter speed controls how long the light strikes the film. For the
same exposure, a change in shutter speed requires an equal and opposite change
in aperture, and vice versa.
There are usually several combinations of shutter
speed and aperture which will give the same exposure. If. for example, the meter
indicates that exposure will be correct at f/4 and 1/60 sec., you usually have other
combinations to choose from. Some of the combinations in this example include
f/5.6 at 1/30 sec. and f/2.8 at 1/125 sec. The two main considerations involved in
selecting one particular combination over the others are the subject’s motion and
depth of field; each of these affects the way a picture will look. You can control
the effect of a picture simply by choosing a certain shutter speed and aperture
combination.
The next three sections provide information which you may find
useful whether you are using the camera manually or automatically with an AE
accessory.
