Post processing: Get Vibrant colors without increasing contrast

This easy Photoshop post-processing technique shows how to transform a dull looking photo coming out of a digital camera and get the vibrant colours it should have. Most cameras, even pro's models, under achieve the colours giving the maximum possibilities for post-processing. With this simple technique, we're using Lab colors to increase saturation on all colors but not increasing edges contrast. It's best used in landscapes, cityscapes, still life and everything but it should be avoided for portraits, which look better (natural) less saturated.
