Howard,



With my scanner, the Canon 4000, there is a huge difference between the RGB 
Color Negative 42 bit setting and any of the monochrome settings. Each 
monochrome setting gives me a single channel to work with, take it or leave 
it. The Color Negative setting gives me three very different channels with 
the option of working with any one, two or all three of them. On my 
particular scanner the red channel is always the lightest, the blue channel 
is always the darkest and the green channel is always in between. I usually 
work from the green but when I have a problem with nearly blown out 
highlights and weak shadow detail in the same photograph I will sometimes 
use two channels, painting from one to the other.



Maybe there should be no difference between channels but with my scanner 
there is and I find the difference very useful.



My suggestion: Listen to all of your friends on this forum and then try 
everything with your particular scanner and see what works best for you.
