Here's what I found:
"Have some pictures to scan? Here are some tips:
the scanner in the grad lab works great for scanning, click on the 'DeskScan' icon to
fire up the scanner. This will ultimately scan to a file. To edit the picture beyond
cropping and adjusting the colors, you will need another program
if you're scanning for web/computer display work like powerpoint, you will not need
that good a resolution, scan as a jpeg, this will keep the filesize reasonable. I
recommend 74-120 dpi.
if your scanning to archive the photos or for publication quality images, you will
want to scan them in TIFF format and at a pretty good resolution, maybe 300 or 600
dpi. They will be huge files, but life has details.
TIFF vs. JPG - tiff is a lossless format, jpg is 'lossy'. If you edit a jpg over and
over again, the image quality will deteriorate. On the other hand, jpgs can be viewed
in a web browser and are much smaller.
when you scan on the mac, put '.jpg' or '.tif' on the end of the filename so PCs know
what to do with them. "
