EXPOSURE MODE
Light reaching the film is controlled by shutter speed and lens
aperture. The proper combination results in a correct exposure.
Shutter speed and lens aperture settings are based on the ISO
speed set for the film in use and the operation of the camera’s
exposure control system.
The relationship between aperture and shutter speed is as
follows: For example, a shutter speed of 1/500 sec. admits half
the light of 1/250 and double the light of 1/1000 sec. An aper-
ture of f/8 admits half the light of f/5.6 and double the light of
f/11. If the correct exposure for a scene is 1/500 at f/8, then we
can also select 1/250 at f/11 or 1/1000 at f/5.6 and achieve the
same exposure results, and so on.
In selecting the exposure control mode, you can choose
whether you want to set the shutter speed and/or lens aperture
automatically or manually.
The Nikon F5 camera offers four types of exposure modes:
Programmed Auto (¡), Shutter-Priority Auto (™), Aperture-
Priority Auto (£) and Manual (¢) exposure modes.
