Here's a LO I did for the 10.04.08 Saturday Special challenge at ScrapMatters, on selective coloring. It's a technique I use quite often, especially for pictures that did not turn out very well (here's an example).
I love the expression DH has in this picture, but the background of our kitchen was pretty distracting, so the selective coloring worked out just perfect.
