Do the scanners with three photomultiplier tubes do a better job?
I would think, not having tried it, that scanning all three colors and
then desaturating the images would be the best way. When doing research
in the 1970s, using TV cameras, if I had to use one channel only, the
green channel was the best one to use for monochrome, but adding up all
three was somewhat better. For the regular color cameras that produce Y,
C1, and C2, the Y was the one to use.
