You could even reduce the noise in LAB, too.
Sorry, I'm starting to sound a bit evangelical about LAB mode. I'll get my coat...

I'm author of the tutorial on HALF-LIME. If you read Dan Margulis's later book
Amazon.com: Professional Photoshop: The Classic Guide to Color Correction (5th Edition): Books: Dan Margulis, you will be surprised! Dan Margulis considers LAB mode correction as a "hammer" tool in color correction, and accurate RBG color enhancements and blending as the best choose if the original is tagged as RGB and destined to RGB color space.
