Remove your Chromatic aberrations

A little know feature in Adobe Lightroom- Remove “Latteral” Chromatic Aberrations dramatically improves images from DJI Phantom3’s

If your first question is “What’s a Chromatic Aberration?” here’s basically what it is: it’s when you see either a purple or green line around the edges of things in your image. It almost looks like someone took a thin magic marker and traced along the edges of objects (like mountains, buildings, etc.). In the image above, look on the edge of the steps (I’ve zoomed in really tight so you can see it).

This is generally a lens problem (which is why the fix for it appears under the Lens Correction panel), but it can be exacerbated by adding a lot of clarity. Luckily, fixing it it’s easier than you’d think, because in many cases just turning on a checkbox will do the trick.

Click on the Color tab (in the Lens Correction panel), and if you’re seeing Purple fringe, under Defringe, increase the top Amount slider until the purple is gone (just go far enough until you see the purple disappear). If you see a Green fringe, drag the next Amount slider down to the right until it’s gone. I rarely have to do this next step, but if you increase the amount of either and the color isn’t affected, then you can drag the Purple Hue or Green Hue slider left (or right) until you see the fringe disappear. Again, rarely have to go that far, but at least now if you do, you know what to do. Here’s a before/after after increasing the Amount sliders for both the Purple Amount and the Green Amount, plus dragging the Purple Hue and the Green Hue sliders.
