As a starting point, I use Photoshop curves and allow the maximum point of the red channel to be at 100% (230).
I drop the maximum point of green to be about 210, and blue to be about 180. (Actually, I think it was Gordan who gave me these suggested values a few years ago...) Then I drop the midpoint of the curve for each channel: usually blue is the most, green a little, and red just a touch, then basically just fiddle with things until it "looks" about right. It's pretty subjective. -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
