(A.K.A "purple fringe", A.K.A annoying)
Chromatic aberration is a type of color distortion that manifests itself as "fringes" of color along edges that separate dark and bright parts of an image.
Both Lightroom, and Bridge have tools that are specifically for removing chromatic aberration, problem is... they just don't remove enough. Time for the big guns. In this tutorial we will use Photoshop.
