EXPOSURE
Exposure control consists of two parts -
aperture control and shutter speed control.
Th
e aperture works basically
th
e same way
as the iris of
th
e human eye and controls
th
e
amount of light passing through the l
ens.
The shutter, located in the camera body,
varies the amount of light admitted to the
film by opening and closing
at
different
speeds. Together, these two controls deter-
mine the amount of light that strikes the film,
resulting in exposure control.
Using the shutter speed and aperture dials
of the N5005, you can select three different
automatic exposure control modes and one
manual mode.
