With digital cameras a common complaint is the "feel" of the image isn't like film. One of the reasons is lack of chroma separation. This isn't saturation, it is the variation of the non-dominant color channels compared to the dominant one. An example is a shot where the greens all look the same, while in real life there are subtle differences in the colors. Some greens are more red, others more blue or yellow. The only way to achieve this in Photoshop is to edit in Lab.

You can see an example of this kind of adjustment at http://www.darktable.org/2012/02/mast...

The suggestion is to provide a tool in Photoshop to adjust chroma separation. It should allow a user to select a hue range and then adjust the chroma separation for that selected range. It could also allow exclusion of neutrals and/or shadows, since these can be troublesome if chroma separation is enhanced.
