Channels or Channel Mixers
Avid Symphony and After Effects allow you to see the individual chan-
nels as black and white images, and Symphony allows you to blend the
channels together in combinations that include not only red, green, and
blue, but also Luma, Cr, Cb, and an offset percentage.
DaVinci Resolve also provides a similar toolset ( Figure 4.67 ), though
it is called the RBG Mixer and is available in the Color Screen in the RGB
Mixer tab.
The black and white views are handy visual tools, but don't give you
too much more information than the RGB waveform. Here are the indi-
vidual channels for red, green, and blue ( Figure 4.68 ).
Green looks pretty much like you would expect for a black and white
representation of the ChromaDuMonde chip chart ( Figure 4.68 b ), except
