Shortly after Photoshop CS6 was released, Adobe provided a very useful update to users of the Camera Raw plugin: brand new tools for removing CA or chromatic aberration! CA is the fancy term given to the fuzzy “color fringes” that we most often see in shots taken under bright light. It can appear anywhere there is a very strong light-dark contrast, whether darker subject on bright background or brighter subject on dark background.
CA most often takes the form of greenish or purple-magenta fringes, but it can display as other colors, like a reddish-orange. Along some edges you may see multiple colors, as you’ll see in this example! Just zoom in between 100-300%, and as you pan around the subject, check the high contrast edges for colors that don’t match up with reality. Fortunately, there’s a very easy solution that requires only a few clicks to get a good result!
The video above is one example of many techniques you can learn about in my new video training course for Adobe Camera Raw.
