Thanks!
Truthfully, you could do this in any colorspace, but for the sake of speed, Lab makes it easier to clone stuff out. The lightness channel is the only detail channel in the lab colorspace. A and B carry only color information. A carries Red and Green, B carries Blue and Yellow.
By doing this in lab, I could "delete" the detail and not effect the color at all. I only tweaked the A and B channel to give a slightly cleaner look to the edit.
Using Lab space for retouching is an old technique, nothing revolutionary, but having a retouching book that includes Lab techniques is a nice thing to have.
