Over the years I have used an HP ScanJet 4c to scan
prints into my various Web sites. However, some of my archived
materials relating to synagogues are now over two decades old and the
prints are showing color shifts. This is also probably true for the
color negatives. For the moment, most of the images on this web site
have been produced by the HP ScanJet 4c and the Canon CanoScan LiDE 30.
I looked around for a reasonably priced slide and
negative film scanner that not only would produce higher resolution images
than is possible with a new combo flatbed/film scanner, but also had the
ability to correct for color shifts and damage to negatives. The
color shifts in the prints can be seen in the few pictures presented on
the page for The New Synagogue, Egerton Road. The color has shifted
even though the prints have been kept in the dark for most of the past
twenty one years.
I settled on the low-end Nikon Coolscan IV ED,
obtainable for a little over $600. The Super Coolscan 4000 ED and
8000 ED looked appealing, but they were way too expensive for the amount
of use I would make of the hardware. These Nikon systems are
provided with Digital ICETM (Image
Correction and Enhancement), Digital
ROCTM (Restoration
of Color) and Digital GEMTM
(Grain Equalization
and Management) image enhancement technology. The original scans
are approximately 4100 x 2700 pixels at 24-bit color depth (about 32 Mbyte
tif file size).
The Coolscan images on this site will be available in four sizes
to suit various screen resolutions and connection speeds.:
