Thanks to everyone who responded to my inquiry regarding the best
scanning resolution.
The thread appears to have headed in the direction of interpolation
for increasing the side of raw scans and I have looked at the sites
referenced. Very interesting information.
I am wondering, however, in my particular situation if this is an
issue. As noted in my initial message, I am scanning 5X7 negatives to
4 X 6.5" size, and can scan them either at the full optical
resolution of the scanner, which is 2450dpi, or at a lower resolution
for at 360dpi at the print size. As I see it I could print my scans
at 360dpi at up to around 24X36", without any interpolation, which is
surely as large as I want to go right now. So, do I need to be
concerned about interpolation?
BTW, just for the record, a 4 X 6.5" scan of a color negative at 2400
dpi gives a raw file of almost 400mb. Think my most important need is
to replace the 100mb Zip drive with a 750mb version.
