RE: Two tricolor prints
Great, I was hoping somebody that does a living from photoshop would chime in. Thanks for suggesting such a simple solution. If I could only remember it a week from now.|

no need to go to LAB to get the benefits of the underlying math. Try the following:
- Make sure your data is 16-bit RGB
- Create a "drastic" curve layer above the background layer to increase the contrast (using a classic "S curve for example)
- Colors will probably change along with the contrast -- this is typical and usually not desired
- Now change the curve layer properies from "Normal" to "Luminosity" -- saturation will remain unchanged from the original background layer while being independent of the contrast curve in the curve layer
The above delivers the same mathematical changes to the data as making mods to the Luminence layer in LAB.
