Microtek Artixscan 2500

Portraiture is one of the largest segments of photography
that uses medium format 120 film. Almost exclusively color
negative, the challenge is to color correct to achieve
high fidelity in complexion tones with portrait film images.
This high key portrait, which I’ve scanned before,
was reproduced by far the best using the ArtixScan 2500
in the sharpness and smoothness of the image tones as
well as the clean whites of the subject’s gown against
the subtle tints of the background.

In the last year I’ve
had more e-mail inquiries about what scanner to buy if a photographer
has medium and large format film to scan than any other single topic.
Until now I’ve not had a good answer for anyone requiring professional
quality at a price most individuals can afford. Microtek with their
new ArtixScan 2500 has changed that situation very dramatically. This
new scanner does it all, letter/legal-sized print scanning and film
scanning from 35mm through 8x10. On top it is a rather standard flat-bed
scanner. But, toward the bottom of this unusually bulky scanner there
is an almost hidden drawer that slides out and accepts a variety of
holders for all sizes of film. Inside is a dual lens multiple resolution
scanning mechanism that supports 1250dpi scanning of the entire scan
area, 8x14" reflected on top, and 8x10" for transparent material in
the drawer, as well as 2500dpi for a 4" strip on the left side the entire
length of the scan area. This is sufficient to support scanning a 35mm
slide or negative to make 11x14 prints with good reproduction quality
or wall-sized images from 4x5 or 8x10 film.
The resolution is backed
up by 36-bit (12 bit per RGB channel) color depth for scanning and support
for standard 8 bit as well as 12 bit per channel output. Combined with
Microtek’s patented two-level design that supports standard reflective
scanning and glassless scanning directly from the emulsion facing the
sensor, the best quality is assured for both types of scans. (For film
larger than 4x5" a glass support drawer insert is used which still maintains
the direct from the emulsion scanning of the film.) In addition, the
8x10 glass support drawer insert can be used to provide direct from
the emulsion entire roll proof sheet scanning of 120 film and 35mm film
cut in five frame lengths.

This full daylight study of an abandoned cantina in an old
Mexican border town was made on Kodak Vericolor HC film.
The negative density range was far too great to print normally
by traditional means in a wet darkroom. However, the full
range of tones in the negative were easily scanned with
the ArtixScan 2500, providing rich detail from the deepest
shadows to the brightest highlights, reproducing a rich
range of bold to the most subtle colorations in the scene
with great accuracy. |

Color management control for
the scanner for both reflective and transparency scanning is included.
The host computer interface built into the ArtixScan 2500 is SCSI 2. The
software supplied with the ArtixScan 2500 is Microtek Scan Wizard Pro
for the Apple Macintosh and all PC Windows operating systems. This is
a quite comprehensive manual scan control utility that may be used as
a stand-alone or as a Photoshop plug-in on a Mac, or a TWAIN driver from
within applications on Windows.
It has full support for batch
scanning for up to 16 color slides or 24 35mm color negatives as well
as combinations of 120 film frames. Several optional automated functions,
including setting the dynamic range and the black and white points with
adjustable gamut clipping, are supported. Options also include a selection
to color correct in RGB or LCH colorspace, and a broad selection of various
sharpening and descreening filters.
Working With The ArtixScan
2500
To get a feel for this new scanner I chose to scan as many different formats
and kinds of materials as possible. Besides calibrating the scanner for
reflective scanning, I also used it to read an ICC test print target for
the creation of a custom printing profile. After calibrating the film
scanning side, I began my test scans by proofing a recent shoot using
Kodak’s new 35mm Supra color negative films. No film term was supplied
for Supra so a little tweaking was necessary, this went very well, as
did a couple of final scans of single frames at 2500dpi from the set.
(Although there are film terms supplied for four different brands, there
were no film terms supplied for any 120 or 4x5 professional color negative
films.)

All rollfilm sizes and 4x5 can be readily set up so the
color correction for the scanning of several images can
all be done individually and then the actual scanning of
the selected frames is accomplished as a batch saving each
file to your hard drive automatically. This screen shows
the tools available when the LCH colorspace is selected.

Once assured the Artix-Scan
2500 would do a good job with 35mm scanning, I went on to scan a variety
of film sizes including color negatives, transparencies, and silver-based
black and white film negatives. The drawer and the film holder made to
fit the drawer are all extremely well made, robust, and quite efficient
to use. Currently the 120 size is a 6x9 film frame so it does not support
smaller 6x4.5, 6x6, and 6x7cm frames readily. I understand a new adjustable
120 holder will be available later. This was no great inconvenience. I
just took care that the smaller film frames were held flat, which was
little additional bother.
Doing an overview of the entire
scan area and then pre-scanning is quite rapid and works very well, providing
a fine resolution adjustable window for viewing the preview image. (This
took a bit to discover because there is a preference selection to keep
the pre-scan preview in the background, which was checked, and I had to
call tech support to find a solution. This preference needs to be turned
off.)
Once your image is framed,
the color correction tools are straightforward and effective, offering
either a direct update in the preview image or the selection of side-by-side
thumbnail comparisons to make perceptually based adjustments. Unfor-tunately
you have to choose between making adjustments using the RGB colorspace
and its tool set or the LCH and its different tools, which includes selective
color adjustment. This to me was pure frustration because you cannot use
some tools if you use others. Most scanner software, as well as Photoshop
and other image editors, offer RGB and LCH color correction tools which
can all be applied to adjusting an image in just one colorspace.

Black and white silver-based negatives can be a problem
scanning with some scanners because the opaque grains of
silver in highlights can cause insufficient light to pass
through to record detail. The diffuse cold cathode fluorescent
light source of the ArtixScan 2500 avoids this and its high
resolution supports capturing a full range of fine detail
across the entire range of tones in this landscape made
with a 4x5 field camera. |

Despite this small frustration,
I had great success tackling a bunch of challenging images. I was able
to get images demanding very extensive color correction scanned so that
the resulting file utilized the gamut fully, and only required minor tweaking
in Photoshop to be quite ideal. In fact I was very positively impressed
scanning transparencies and negatives in 6x4.5 and 6x6cm sizes and obtaining
very sharp and finely detailed image files ideal for printing at 13x19"
at minimum and easily larger (if I had a larger format printer).
I was also pleased to find
the proofing of entire rolls of negative film can be done very efficiently
and easily. If you do this proof scanning from within Photoshop you have
the choice of enlarging frames on screen to make an immediate, direct
choice, or you can just print a color proof sheet directly, and then discard
the image file and go about making another proof of a roll. At the other
end I also took advantage of the support to scan larger film and obtained
the best and most easily achieved high-resolution 8x10 film scans.
Evaluation And Recommendation
After most of a month working with the ArtixScan 2500, I was well assured
of its consistent ability to output sharp, accurately optimized quality
scans from every kind of image media a photographer is likely to use.
Physically the handling of the materials to scan is quite efficient, particularly
considering the wide range of media sizes it accommodates. And although
I found some of the software function frustrating and not fully supportive
of producing a finished scan that required no post-scan tweaking, it is
just about the best of the utilities provided by any scanner manufacturer
in ease of use and functionality. Having the ArtixScan 4000t 35mm scanner
among my personal equipment inventory, I prefer its slightly different
ScanWizard Pro TX setup for overall efficiency of use compared to the
ScanWizard on the 2500, although it does lack a Hue, Saturation, Lightness
selective color adjustment capability.

Considering the entire range
of specifications and the fact no format is compromised in quality, the
retail price of $4495 is very reasonable. Competitively, a number of other
dedicated multi-format film scanners with a lesser range of capabilities
are even pricier. From my experience with the ArtixScan 2500 I believe
any photographer who does a substantial part of their work with medium
and large format cameras would be very well served by the scanner. I’m
sure I’d be quite satisfied to have an ArtixScan 2500 as the core
input facility in my digital darkroom, whether I was using an Apple Macintosh
or Windows PC computer.
This entire package of all-in-one
scanning and software has a suggested retail price of $4495. For more
