Jennifer -
If your output is photographic, you may find JPEG to be a
better output format choice. The image files will be much smaller.
Now that you know how to control the output format, you should experiment to see
which format works best for you.

That was exactly what I needed to do. The problem is fixed!
Thanks for all the help!

Thanks for the response, Frank. It is sounding more and more like this is a question I ought to forward to the chameleon list - because I am also not sure how to generate 24bit output with chameleon!
I appreciate the much needed direction!
Thanks all!

In addition to fetching data from the remote WMSes as
JPEG, it is also necessary for mapserver to generate 24bit
output (JPEG or PNG24 for instance). I don't know how to
do that with Chameleon myself, but I'm sure there is a setting
somewhere.
I think Ed is right that the problem is 24bit to 8bit color
conversion with correspondingly poor color resolution.
Given sufficient blotchiness from this conversion it can
even appear that spatial resolution is degraded (though it
isn't actually).
Best regards,
