Controlling Exposure
Capturing Images in Each
Exposure Mode
Light reaching the imager is controlled by the 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 and the
operation of the camera’s exposure control system.
The relationship between aperture and shutter speed is described in the
following example:
• A shutter speed of 1/500 second admits half the light of a shutter speed
of 1/250 second and double the light of a shutter speed 1/1000 second.
• An aperture of f/8 admits half the light of an aperture of f/5.6 and
double the light of an aperture of f/11.
• If the correct exposure for a scene is 1/500 at f/8, you can select 1/250
at f/11 or 1/1000 at f/5.6 and achieve the same results.
In selecting the Exposure mode, you can choose whether you want to set
the shutter speed and/or lens aperture automatically or manually.
Your camera has four exposure modes:
• Programmed Auto ( P )
• Shutter-Priority Auto ( S )
• Aperture-Priority Auto ( A )
• Manual ( M )
NOTE: When you set any exposure mode, first set the aperture ring of the
CPU NIKKOR lens to its minimum aperture setting (largest
f-number). If the lens is not set to its minimum aperture setting,
