All you have to do is to reduce the size of the image to 600-700 pixels
long or high. Don't bother changing the resolution as it makes no
difference to the size of the file that results.
I scan at 4000 or 5400 ppi, save the resulting file for turther use,
normally as a .jp2 or compressed .tif. For web use I then reduce the
longest dimension to 750 pixels, save it as a .jpg (normally at 80-90%
quality, but aiming to keep the file size to less than 100Kb). I then
make sure that the file information is complete (using Photoshop
Elements) with my name, a caption and a copyright notation before
sharpening ever so slightly and saving it again.
The file is then ready for publishing. I am becoming more sensitive to
the Gamma setting of the destination monitors (since I have a Mac which
normally operates at 1.8), but that'[s about it.

get the original scan to compress sufficiently and still produce a good

this to
72dpi in several steps with a little unsharp at each stage. Mostly this
works for an 'acceptable' result but sometimes (and in this case) the
end
result is too poor to use.
Does anybody know of an idiots guide to scanning for screen output? I
suspect I need to rescan at a lower initial resolution, maybe 1600dpi?
Also
I'm now using, and very impressed with, Kodak Portra 400 UC instead of
my
usual Fuji Superia 200.
Thanks
