I found brightness/contrast/gamma controls in xsane. After find out 
the right position from 3 parameters, it works.

Back to my preferred gscan2pdf:

It can call gimp and it is possible to make the same after scanning 
with the internal files from gscan2pdf. It gives more control for 
the user, but I can not see a simple procedure to modify all scans 
in the job in one step...
