I may miss something but I believe that extractplanes neither 
changes nor does not change the range, it simply outputs the 
data as it is stored in the input plane (1:1).
Depending on the input colour space, this may lead to 
unexpected results.
But I have to admit I had not used the filter before.

Please try to fix your quoting, Carl Eugen
