Easily Remove Chromatic Aberrations in Photos

| February 20, 2011

TIP: If you view the video in full screen you will be able to see the fringing
in the image more clearly as it is being fixed.

I learned this technique via research on the web and it saves me so much time I thought I would share it with you.  Chromatic aberration is something that plagues many images we photographers work with for various reasons.

Instead of trying to redefine it, below is the definition for chromatic aberration at Wikipedia (see the full Wikipedia page here):

In optics, chromatic aberration (CA, also called achromatism or chromatic distortion) is a type of distortion in which there is a failure of a lens to focus all colors to the same convergence point. It occurs because lenses have a different refractive index for different wavelengths of light (the dispersion of the lens). The refractive index decreases with increasing wavelength.

Chromatic aberration manifests itself as “fringes” of color along boundaries that separate dark and bright parts of the image, because each color in the optical spectrum cannot be focused at a single common point. Since the focal length f of a lens is dependent on the refractive index n, different wavelengths of light will be focused on different positions.

How do you fix it?

More important than the definition is how to get rid of it. In low resolution images it is not a terribly big deal. But blow that chromatic aberration laden image up on a nice $150 canvas and you are going to be bummed out! It is best to take care of it before you spend the big bucks. The video above it a super easy way to deal with the phenomenon known as chromatic aberration.

I hope this saves you as much time as it saves me. Happy President’s Day tomorrow and thanks as always for visiting!

  1. Great tutorial Lee – super helpful, and a much quicker fix than how I’d previously removed CA!

    Thanks guys! Glad you found this useful. I am working on some masking techniques that are really great too. Will share once I get a handle on them.
