[sane-devel] Why does XSane set Gamma = 1.0
Fri, 3 Sep 2004 12:22:27 +0200
Hello Oliver (Rauch) in particular,
I have a (may be silly) question:
Why does XSane set the scanners' Gamma Table to an equivalent Gamma of 1.0
before a preview scan is started?
NIASH scanners work best with a gamma value of 1.6.
Gamma=1.0 will definitely produce scans that are far too dark.
A workaround is:
troughing away the feely editable gamma-table in the scanner options and
only offer the analog gamma correction scalar, so that the gamm table cannot
But this would take away a degree of freedom, that might be useful for some
On the other hand:
Using the scanner with a gamma that is definitely bad, is also no good idea.
Especially for "Newbies".
Thanks your for your answer
