Thanks for the explanation, Olaf.
As you say, when using Image Scan! for Linux, then 'Document' setting
does produce a slightly lighter 'white' than the 'Photo' setting, but
not very significantly, and not enough.
If iscan would just remember my settings, that would be the end of the
story, at least for iscan...
I assume from your explanation that nothing is going to make this white
correction automatically for me, in any app, but is there nowhere in the
whole chain of events I can make a once & for all manual adjustment?
Thanks for your patience ( as well as expertise, of course)!
