11 Intelligent inking
When inking, I usually work the shadow areas as spot colours. It helps me to better understand the negative space in the composition before moving on to colour. Then I paint and render on the black colour. If this colour is too heavy, I can always use a Difference or Screen layer to make it lighter. If that fails, you can select a colour range to modify it. Personally I prefer it this way, because I like strong contrasts.
