Remove Purple or Green Fringe?

Go under the Filter menu and choose Lens Correction, then zoom in really tight on an area that has this color fringe problem (these are chromatic aberrations). Now, click on the Custom tab and drag the Chromatic Aberration slider that matches the color fringe problem you’re having to the right until the color fringe is gone (you might have to move more than one slider). That being said, I prefer to use Camera Raw’s Lens Corrections to remove chromatic aberrations because it has an automatic function you can turn on, and often doing just that will fix the problem (see Chapter 3 for more). To do it this way, go under the Filter menu and choose Camera Raw Filter, and then click on the Lens Corrections icon (it’s the fourth one from the right, under the histogram). In the Lens Corrections panel, click on the Color tab at the top of the panel, and then turn on the Remove Chromatic Aberration checkbox. If that doesn’t fully do the trick, you can drag the Purple or Green Amount sliders to the right just enough to where the fringe goes away (don’t forget to zoom in tight on a fringe area, so you can clearly see the problem before adjusting the sliders. That way you don’t overadjust). One more thing: those Hue sliders under the Amount sliders are to help you target the exact hue of purple or green that’s causing the problem. So, if raising the amount didn’t fix the problem, you might have to move a Hue slider until it targets the right hue of purple or green to make it go away.
