Appendix B. Using the Optional Universal
Transparency Cover (UTC)
This scanner is capable of capturing transmissive images with a UTC, which
gives you the capability to scan slides and transparencies. It can be difficult to
get a great scan from negatives. Negative film normally contains an emulsion
that affects the color of the image when scanned. Other transmissive images
may appear clear, but negatives often have a muddy, brown, gray or orange
tint to the image.
The VistaScan software contains a “negative” option for compensating for the
inherent color bias of the emulsions. VistaScan is able to neutralize the cast of
whichever emulsion type is applied to the negative, based on the type of the
negative.
To achieve the best scan from a negative:
•
Scan negatives and slides at the highest optical resolution the scanner
supports, which is 600 dpi for this scanner. You should also try scanning
at 1200 dpi to see which resolution works best for you.
•
Make sure you select only the image wh en cropping, and do not include
any extra background material.
