In this week’s free Deke’s Techniques episode, Deke dispels the myth that using the Lab mode to adjust color is inherently destructive. In fact, he’ll show you how to correct the color of this ‘70s-esque flower child:

Sure, maybe the Groovy filter effect is what you want, but frankly, despite those perfectly applied blossoms in her hair, those eyebrows don’t look very “I just got out of my VW van on a cross country trip to San Francisco” to me. Deke’s technique this week ensures that both her skin and her histogram are as smooth as those perfectly coiffed eyebrows:

Along the way, you’ll see how Deke makes color decisions in the Lab mode in order to bring this girl back to the colors of our modern age (and eventually back to RGB, which is the final trick here).

If you’re a member of lynda.com, Deke’s got an exclusive movie this week in which he shows you how to take the refinement to the next level in Camera Raw while keeping it in the Lab mode (which is impossible!) If you can’t believe it yourself and you’re not a member of lynda.com, you can get a free week’s trial at lynda.com/deke in order to check it out.

That’s Deke for you, pretending things are impossible then deftly showing you how to actually do them every week.
