Virtual
Drum Scan Info
At WGS we use the finest virtual drum scanner
available: Imacon
FlexColor 848. Unlike conventional drum scanners, it does not
utilize mounting fluid to adhere negatives or slides to the drum. Since
no liquids are used there is no risk of damaging precious negatives. Imacon
uses a "virtual drum" sharing the characteristics of an ordinary
drum scanner but without the nasty glass rim.
This scanner allows for true 16
bit per channel scanning. The raw scan generates twice as much data as
an ordinary scan, without "electronic" interpolation, for optimal
results. Files are then transformed to 8 bit suitable for use in Photoshop
and other applications.
Note to Photographers:
This scanner is particularly valuable to photographers
who need to create an optimal quality scan for an archival fine art print
(giclée). The original negative or transparency is never mounted
on glass, avoiding color flaring and maintaining a straight glass-free
optical path, something no ordinary scanner can approach. The original
is never mounted in liquid, particularly valuable with color negatives,
Polaroid and other delicate media. The scan has a very wide dynamic range,
with a Dmax of 4.8! All personnel at WGS are photographers, not just technicians;
we share an in-depth understanding of tonality, color fidelity and film
characteristics.
A Dirty word
Film, improperly stored or processed, may have
extreme amounts of imperfections on, or beneath, the surface. Following
Industry Standard Guidelines, we "spot" our scans to
eliminate surface dust. Scratches and imbedded particles due to faulty
processing, drying or handling may exceed our responsibilities. Duplicate
negs & slides are extremely likely to have a considerable amount of
imperfections in and on the image. You may incur additional charges for
cleaning duplicates and very dirty originals.
How big?
Most printers work well at 300 dpi (dots per inch, often referred to as "ppi"; pixels per inch). Our Epson 9800 printers, utilizing Ultrachrome pigmented inks, works best at 360 dpi. You should request your file to be made so that the final image size of your file will be output at, typically, 300-360 dpi.
Too confusing?
Just request your scans at the largest operative
size within a given price range. Leave the "size" column blank,
and fill in the "price" on our WGS order form.
In addition to scanning, we can print your file
using archival processes, as well as image modification, retouching and
special effects.
No charge for archiving your files.
