COOLSCAN IV ED
2900 dpi 35mm/APS Film Scanner
The Coolscan IV ED is a high quality, high-speed desktop film scanner that lets you scan,
enhance, catalogue, preserve and restore images from positive and negative film. And
although “entry-level” from Nikon’s perspective, this affordable scanner incorporates
features, technology and quality previously only available in high-end film scanners.
Designed for photo enthusiasts who are looking to digitize images for a variety of
applications, including sending photos by e-mail, designing web pages, or archiving
and cataloguing images to preserve memories captured on film, the Coolscan IV ED
boasts the most advanced imaging hardware and software technology available. It
integrates Nikon’s exclusive ED glass, proprietary LED technology, and easy-to-use Nikon
Scan 3.0 software to scan images with push button simplicity. Last, the scanner includes
Applied Science Fiction's Digital ICE3 suite of sophisticated digital enhancement tools.
Using the software suite, you can digitally restore images that have been unusable
because of fading, under or overexposure or scratches on positive and negative film, as well as improve upon an image's
overall appearance for optimal scans of originals. The perfect complement to any SLR, the Coolscan IV ED offers photographers
a complete imaging solution for bridging the gap from film to digital technology.
High Quality Scans
◆ Custom 2870-pixel CCD automatically
reduces noise, and offers wide dynamic
range to clearly reproduce the scanned
image. Offers high-resolution scanning at
2900 dpi for exceptionally sharp images
with superb reproduction of solid
objects and minute detail. For better
color registration and less color shifts,
Nikon uses only one CCD sensor.
◆ Precise 12-bit A/D conversion input and
16-/8-bit output deliver image data in 68
billion colors.
Nikon ED Glass
◆ Employing ED (Extra-low Dispersion)
glass elements, the Coolscan IV ED’s
Scanner Nikkor ED lens minimizes color
aberration and image distortion to deliv-
er sharp delineation and produce bril-
liant results. Previously available only in
professional SLR lenses, ED glass mini-
mizes chromatic aberration allowing
lenses to offer superior sharpness and
color correction. Chromatic aberration is
a type of image and color distortion that
occurs when light rays of varying wave-
lengths pass through optical glass.

FEATURES
EQUIPMENT LEASING AVAILABLE
Digital ICE (Image Correction and
Enhancement)—
This technology works by reading surface
defects of color film and recording them
in a separate channel. A proprietary algo-
rithm is applied to the image removing all
the defects within the scan, and leaving
the original film intact. Digital ICE elimi-
nates virtually hours of Photoshop
retouching time, and makes previously
unusable images usable. Newest version
offers a number of improvements, allow-
ing you to achieve even finer control
when applying Digital ICE to your scans.
Digital GEM (Grain Equalization
Management)—
This technology, through a complex
set of proprietary algorithms, reads
the grain details in the film and
extracts all the vital data related to
image quality, while minimizing
grain clutter; Working in a similar
way to Digital ICE, users of ISO 100
speed film or higher will see images
that look as though they were taken
with much lower speed film. This is
especially valuable to newspaper
and magazine photojournalists.
Digital ROC (Reconstruction of Color)—
This technology, customized to the characteristics of the Nikon film scanner, will
automatically rebuild the lost color values in positive or negative film, and recreate
instant color-corrected digitized images. In addition, Digital ROC will correct for
under or overexposed negative and positive film and create a baseline standard, or
“normalization” of color from scan to scan; especially useful with negative film.
DIGITAL ICE
Digital ICE incorporated in Nikon Scan 3.0, eliminates all surface defects, corrects
color and exposure, and automatically reduces the film grain in a scanned image.
