Exposure; Shutter Speed Dial And Aperture Dial - Nikon N4004s Instruction Manual

EXPOSURE-----------------------------------------
Exposure control consists of two parts-aperture control and
shutter speed control. The aperture works basically the same
way as the iris of the human eye and controls the amount of
light passing through the lens. 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 determine the amount of light that strikes the film,
resu lting in exposure control.
Using the shutter speed and aperture dials of the N4004s, you
can select three different automatic exposure control modes
and one manual mode.
