WHAT
IS
VARI-PROGRAM?
Programmed exposure control enables the camera's computer
to automatically adjust both lens aperture and shutter speed for
the correct exposure. The N90 camera's Matrix Metering
System determines the correct exposure, applying exposure
compensation as deemed necessary by the computer's
program. However, other factors can affect the picture,
including the use
of
different shutter speeds and different
apertures.
The N90's Auto Multi-Program
is
designed to coordinate the
selection of shutter speed and aperture for average situations.
It guides the exposure control system into using reasonably
high shutter speeds to avoid blur due to camera shake. The
N90 incorporates a versatile Vari-Program System that gives
you the option to choose from different programs, each
designed to accommodate different picture-taking situations.
Please review the concept behind and recommended use for
each program, using each
as
described, or
in
a different way to
express your own picture-taking creativity. Once you
understand how each program operates, you'
ll
be able to
experiment, using each program for an application different
from its originally intended use.

Please note that the effect achieved by using each
Vari
-
Program can be reproduced with the use of other exposure
control methods such as Shutter, Priority Auto, Aperture-Priority
Auto and Manual. But with Vari-Program control, you allow the
camera's computer to take care of
all
exposure control tasks
while you concentrate on composition. This versatility
is
one
of
the highlights of the N90 camera's advanced exposure control
system.
