Unfortunately no : 1) because Twain interface does not allow, 2)
because you can't tag at the scan soft level.

Yes but the warning should be "no profile embedded". Just the gamma 
is to be "transferred" to PS. 


In that case, one of two things can be wrong.  Your scanner

Yes : this is exactly where I can't find out. I understand my 
question is very specific and not to be put on the DBWTP group.

Thanks for the care and help Steve. This LS50 scanner model is great 
but I find the driver really flimzy or at least very obscure...

While you're on-line, I have a question of another type for you : I 
believe you have a 4800. I have an air buble in the yellow line 
(which apparently is common). Should I (really) worry about this or 
not. If so power cleaning is the only option ?

Thanks again
