EXPOSURE

• An exposure reading is taken by pointing the camera at the subject while looking through the viewfinder.

• The build-in meter measures the light being reflected back from the subject to determine the correct exposure rehired.

• Then set the aperture and shutter speed combinations accordingly.

There are 4 factors that need to be taken into account when determine the correct exposure for a picture:

• The light level
• The film speed
• The aperture
• The shutter speed

• Before taking a picture, measure the light levels - this may be done automatically.

• The aperture and the shutter speed produce the exposure.  These can be used in various combinations to get exactly the same amount of light to the film.
