number of images that can be recorded on a floppy disk
depends on whether the image is recorded in the field"

disk. The field mode provides poorer resolution
because there are less pixels per picture. The FRAME
MODE uses two tracks per image and allows 25 images
to be stored on one floppy disk. The frame mode
provides higher quality because more pixels per image
and colors that are created electronically by the intensity
and the color of light striking an image sensor within
the camera. This analog signal is the same type of signal
used to record most motion-video images. It is also the
same type of signal used in conventional television.
Many still-video cameras have a playback capability

it can be modified or printed in a digital-imaging

of these digits represents densities and colors created

back to capture high-resolution color or
black-and-white images. The Nikon body operates
similar to a camera with conventional film. The major
compared to the DCS back is that the image area of the
DCS is only one half of the size of a 35mm-film frame.
This change in image area affects the effective focal
length. For example, a conventional 35mm lens
becomes a 70mm lens with the DCS. The Nikon F-3
functions, aperture settings, shutter speeds, and light
metering operate the same as with film. Three major
components that make up the Kodak DCS are as
follows: an electronic back, a camera winder, and a
digital storage unit.
means the CCD is capable of recording about 1.3
million pixels. The color back equates to film speeds
of 200,400, and 800. The monochrome back equates
to film speeds of 400, 800, 1600, and 3200.
