Jeffrey, the densities add, but you don't get more tones since at a given
point, you simply add up three densities. If you do multiple exposures,
you can get more tones by varying the exposure as I've explained in
another mail. This then gives you 256 grayish tones + 256 black tones (ie
in the case of a duotone).
