It would be helpful to me and hopefully others to know what settings
you have settled on, reconciling the trade offs between detail, scan
time, and storage. Epson V500 or similar. I know that for ultimate
quality, use the highest settings -- for Epson V500 those are 6400
dpi, 48 bit and ICE -- if I zoom on a detail enough in PhotoShop I can
tell you on my monitor which scan was 3200 dpi and which was 6400 dpi,
but I haven't experimented yet with different color depths. What would
be helpful is to know what you use for a given end result, such as
print size or viewing on a TV. If we get enough responses, this will
be a very useful thread to help people use only the highest setting
necessary for a given end result, where anything higher is not
perceptible for a particular end use. If you have also scanned
negatives (color or B&W), that information will be helpful, too.
Thanks.

Here's some posts that came to me by email:

I just try to scan at a high enough resolution that I could print the
size that I end up with at 300dpi.

I always save my most important pictures/scanned slides in the .tiff
format. Opening a .jpg file, saving it, closing and opening again, etc
is analogous to making a xerox copy and then a copy of the copy and
then a copy of the copy of the copy...the quality greatly deteriorates

Well don't open it, do things to it and then save it! Keep a mster
copy that you *never* change (copy to CD if necessary). Then make
copies of the master JPG file to work on.

Then, as long as the 'master JPG' file is satisfactory (i.e. stores
enough detail etc.) you'll never lose anything.
