Wow, so many newbies on this thread...
First, you are in trouble because you need lots of free disk space to use
Photoshop, and lots of free disk space to store images of any quality. So
step one is get a new hard disk.
Second, you want quality reproduction. To me, that means you want to
descreen the halftones (take out the little halftone dot patterns) and
perform tonal and color corrections so that you get your quality
reproduction. If you start by scanning as a highly compressed JPEG (a
lossy format), you throw out quality with every save, and as you do your
corrections and save as JPEG again and again, well, your images will be
trashed by the end. JPEG is a great final file format, but not great for
So I would say, scan into Photoshop format FIRST, to keep the original
scan's quality level while you do your various corrections and repeatedly
save, and finally save as JPEG Medium Quality LAST. (If your tests show
that JPEG Low Quality works well enough, then go with that.) Also, if you
are scanning black-and-white photos, you can save lots of disk space by
scanning in grayscale.
But, you never said what your desired level of quality was. Web page? Copy
machine? Printing press? Your answer to that one question will radically
alter your choices for things like resolution and compression.
Save yourself a bunch of headaches...go to the bookstore and get Real
World Photoshop by David Blatner and Steve Roth. (I am not affiliated with
them in any way.) I can't imagine anyone going into a project like yours
without reading a great book like that. Scanning, corrections, formats,
printing, it's all in there.
