This week’s technique from Deke is about using Photoshop to fix a common problem that occurs in photographs: transverse chromatic aberration, otherwise known by its far less daunting name, color fringing. This phenomenon— caused by light breaking up into its primary components— leaves outlines of aberrant color around the edges in your photograph. Have no fear, however, because despite its daunting name, transverse CA is easily fixed in Photoshop. In this week’s free movie from Deke’s Techniques, Deke not only illustrates how the phenomenon occurs, but also shows you how to fix it, armed with the Lens Correction filter and a modicum of analytical ability (or simple trial-and-error).

Check out the before and after results on this photo of Venice’s Rialto Bridge, and notice how the stripes of color around the statue and windows have disappeared in the image on the right.

For members of the lynda.com library, this week’s exclusive members-only movie will show you a second approach for removing transverse chromatic aberration with Adobe Camera Raw. Either way, it’s a quick technique that will help you make quick work of this common problem.

Join us each week for another free technique from Deke!
