Nikon Camera N90 - Manual (Page 102)

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 reasonabiy
high shutter speeds to avoid blur due to camera shake. The
N90 incorporates a versatiie Vari-Program System that gives
you the option to choose from different programs, each
designed to accommodate different picture-taking situations.
Piease 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.
