Forgive me for being a wet blanket but scanning a photographic
print at a resolution of 4800 dpi is a mistake. All that has
happened is that you have made a very large image that will be
a problem to work with. However, the original print certainly
doesn't have more than 600 dpi of information in it and quite
possibly a significant amount less. But don't take my word for
it. Take a look at Wayne Fulton's http://www.scantips.com/, in
particular this page: http://www.scantips.com/basics08.html

You should post a section of the image to some group like
alt.binaries.comp-graphics or to a web site so we can see
what is the problem and offer some useful advice. It would
just be guesswork to go only by your description I'm afraid.
It would be a good plan to post only a 300 dpi version of the
image, which would be much more manageable in size and would
contain sufficient the detail.

You could probably print the image at twice its original size
in cm. Any bigger and you'd notice that detail is missing from
the image.

Only when I know what's wrong with the image. I'm afraid
I won't give you any advice on how to use Photoshop - you
can ask Chris Cox for help with that :)
