Until recently, a 4000dpi
Nikon 35mm film scanner would have set you back at least $1000, but
that has changed with the introduction of the Coolscan V ED. Even at
$599 this model is absolutely loaded with advanced features such as
an ED (extra low dispersion glass) lens for superb image quality, an
improved processing algorithm for superior scans of color negatives,
an enhanced color management system, plus a comprehensive range of image
enhancing tools. Two brand-new features are available in the Nikon Scan
4 software: Digital DEE (part of Digital ICE4) and Scan Image Enhancer
for automatic brightness/color/contrast correction.
Although this is a pro-caliber scanner in some respects, the entire
installation process takes a mere 15 minutes. An Easy Scanning Guide
CD provides guidance on the setup and operating procedure while the
Nikon View software offers simplified viewing and archiving of scanned
images. Load a slide or negative, complete a pre-scan (a 30-second process)
and the Coolscan V ED will generate a high-res scan in under a minute.
The automated image enhancement tools are great for maximum simplicity
but the Nikon Scan 4 software also offers numerous manipulation utilities
that will satisfy the advanced imaging enthusiast.
Optical Resolution: 4000dpi
Dynamic Range: 4.2
High Speed: USB 2.0

Coolscan V ED can generate scans with pleasing exposure,
color balance, and saturation as well as high sharpness.
While digital capture with a digital SLR camera has some
advantages, a 4000dpi scan offers nearly 22-megapixel resolution.

Using The Coolscan
In order to test the automatic enhancement features, I selected some negatives
and slides that did not exhibit any obvious technical problems. Using
only the most basic one-click features for autofocus and exposure, the
Coolscan V ED produced very good 4000dpi scans in 55 seconds with my fast
Pentium IV computer and USB 2.0 connectivity. Some of the scans called
for a minor adjustment in image-editing software but none required any
major correction. According to Nikon's claims, a high-res scan can
be made in as little as 38 seconds. Presumably, that requires disengaging
all of the scanner's software features. But 55 seconds is still
pretty fast for such a high-res scan.
As with any scanner, additional image correction features increase the
processing time. For example, Digital ICE dust and scratch removal--in
the Normal mode that's suitable for most images--added 30 seconds,
but saved far more time in post-scan cleanup and retouching. The automatic
Scan Image Enhancer added another 30 seconds, but this feature was not
often necessary; it was most useful with slides and negs that exhibited
poor color balance. Overall, I judged the Coolscan V ED to be a fast scanner,
and lightning fast when compared to some 2800dpi machines that require
several minutes to complete a basic scan using only autofocus and the
standard autoexposure feature.
After optimizing the best scans for printing in Photoshop CS, I made some
13x19" outputs at 300dpi, using an Epson Stylus Photo 2200. These
oversized prints are absolutely gorgeous, obviously superior to any that
I have made from a 2800dpi scanner. I would also be proud to send the
resultant 55MB files to photo buyers, confident that they would be satisfied
with the image quality.
with a slide or negative that's well exposed and the
Coolscan V ED can produce a beautiful scan using only the
most basic one-click adjustments. (Autofocus and Autoexposure.)
Advanced Software Features
Anyone with some experience with scanner software or a pro-caliber image-editing
program will want to take advantage of the many additional tools that
allow for perfecting a scan. Some of these will be familiar to anyone
with digital darkroom experience: Curves, Levels, Unsharp Mask, Color
Balance, and other conventional utilities are all accessed with a convenient
interface. Other features are unique to scanner software, and in some
cases, unique to Nikon. Some of these are worth considering in additional
detail. Do note that each of the following increases scanning time considerably,
so use them only when necessary.
Digital ICE4: In addition to Digital ICE for dust and
scratch removal, this utility includes three additional tools. Digital
ROC (Reconstruction Of Color) restores color in faded images; Digital
GEM (Grain Equalization & Management) nearly eliminates visible film
grain; Digital DEE (Dynamic Exposure Extender), the fourth feature in
ICE4, is an entirely new option and it's discussed in detail.
I found ICE to be very effective although the resulting scans were slightly
soft; that was easy to correct with Unsharp Mask in Nikon Scan 4 and later,
using Unsharp Mask in Photoshop before making a print. Because my files
do not include faded slides or negatives, I was unable to test ROC, but
friends who own other Coolscan models indicate that this tool works surprisingly
well. GEM is a blessing when scanning grainy film, producing a smoother
image. If you plan to use ICE or GEM, apply Unsharp Mask in the scanner
software to restore sharpness. As a starting point, try the following
Unsharp Mask settings: Amount, 35 percent; Radius, 1.5 pixels; and a Threshold
level of 4.
new Nikon Scan 4 software provides an exceptionally wide
range of image enhancement features to satisfy imaging enthusiasts
at all levels of experience.
Digital DEE (Dynamic
Exposure Extender): Reminiscent of the Shadow/Highlight tool
in Photoshop CS, DEE was designed to recover detail from bright highlight
areas and from dark shadow areas. While no software can produce detail
that was not recorded by the film, DEE was quite useful when scanning
contrasty slides and negatives. In my estimation, the default level is
set too high for most images. I recommend starting with a moderate DEE
level (such as 25) when experimenting; increase it as required for a particular
Note: You cannot preview the effect of features such as Scan Image Enhancer,
Digital DEE, and Analog Gain in "real time"; the preview image
does not change to reflect the corrections produced by the software. In
order to view the "enhancing" effect, click on the "Preview"
button to produce a new (adjusted) preview image.
Analog Gain: An uncommon feature available in the Nikon
Scan 4 software, this one is designed to correct "severe"
underexposure by increasing the length of time the film is exposed, resulting
in brighter output. As you might expect, no software can work miracles
and there is a tradeoff. Scans made with Analog Gain exhibit more digital
noise as well as a slight loss of detail in extremely bright highlight
areas and in highly saturated colors. I found this feature to be most
effective with slides or negatives that were dark overall, without excessively
bright highlight areas.
Analog Gain is not intended for correcting minor underexposure; use other
scanner tools such as Digital DEE, Levels, and Curves for such problems.
Reserve Analog Gain for film that was underexposed by more than a stop
and requires a major corrective effort. Experiment to find just the right
intensity level and this feature will save some images that you might
Use the right combination of Nikon Scan 4 tools and your images will exhibit
extraordinary definition of intricate detail, high color fidelity, pleasing
skin tones, plus great highlight and shadow detail. As you might expect,
the ultrahigh resolution scans do make film grain quite visible, even
with ISO 100 negatives and slides; if you prefer smoother images, apply
order to correct most exposure errors, it's worth
using a combination of adjustment tools. For this image,
I started with Scan Image Enhancer and then applied Digital
DEE plus a bit of tweaking of Curves and Levels in the Nikon
Scan 4 software.
Review the Specifications chart and you'll find a few additional
Coolscan V ED features that I have not discussed in detail. The most notable
include an extensive color management system and 16 bit per channel color
output, great for making substantial tonal or color adjustments in post-scan
processing. Do note, however, that the 16-bit files are huge (110MB) and
that only Photoshop CS provides comprehensive 16-bit support.
The ($1099) Nikon Super Coolscan 5000 ED, a pro level 4000dpi model, offers
some advantages such as greater speed and an even wider (4.8) dynamic
range for more detail in contrasty slides. Still, the Coolscan V ED is
a truly effective scanner that met all of my needs during the test period.
For long-term use, I might miss two other features available only with
the more expensive Coolscan models: compatibility with extra-cost accessories
for batch scanning 40 negatives or 50 slides and the multi-sampling option.
The latter can reduce digital noise in shadow areas but it's not
essential for most images and it significantly increases scanning time
at 16x, the most effective setting. If you're not sure as to which
Coolscan would best meet your own needs, compare their specifications
on the Nikon website.
The included and powerful Nikon Scan 4 software is designed to satisfy
advanced photo enthusiasts who demand additional problem solving tools
for making great scans from "difficult" slides and negatives.
Granted, the full slate of options involve a steep learning curve, and
that calls for patience and some experimentation. Take the extra time
to become proficient with all aspects of the software and the Nikon Coolscan
V ED will reward your efforts with beautiful scans of professional quality.

mentioned in the text, this tool can often produce a significant
improvement that would be difficult or impossible to achieve
with more conventional tools.
