Hello,
Sorry for this late response..I have tested scanimage with Red Hat 8 and Red Hat 9.
The output in Red Hat 9 is darker compared with that of Red Hat 8 but exactly the same settings were used..
You have said in your previous reply that xsane should not modify gamma settings automatically..I`m quite confused with the use of the options..How may I be able to do this?
Thanks a lot,
PMG

I haven't heard about such a behaviour. Can you reproduce it with
scanimage? Maybe the scanner wasn't warmed up completely in one of the
tests?

Yes, if you don't use any of the color enhancement settings. E.g. make
sure that xsane doesn't modify your gamma settings automatically.
Bye,
