Removing Chromatic Aberration

Article by Giuseppe Sapori

Chromatic aberrations appear as a colored stripe on sensitive areas; these areas are usually characterized by strong contrast. Chromatic aberration is usually colored cyan, green or blue, but it can have many different shades.

Among the ways to remove chromatic aberration, in this tutorial I’ll show you a simple method to remove them through the use of layer masks.

I’ll be working on this image

Duplicate layer (cmd+j) Mac (ctrl+j) Pc

Go to filters>Blur>Gaussian Blur, set the opacity and then the slider around 14

Select blending mode “color”

At this point the image is apparently normal again.

Select a layer mask on the bottom menu of the palette instruments or go to Layer>Vector Mask>Reveal all and press ( cmd + i) mac  (ctrl+i) PC to hide the content of mask.

Now select the brush tool with the white color and change the opacity. Set the opacity slider value on a range 20% -50% (max) depending on how the chromatic aberration is marked.

Now, start painting the areas with chromatic aberrations to remove them. The layer mask should look like this

    One of the best ideas ever!

    It seems like magic. I worked on an old image, token with a kit-lens on the Canon EOS 450D.
    This Image had a lot og CA´s, and that inside a few trees.

    Never i could leave all of the CA´s in that image, even I worked hard on that. But with your great workflow I did it in just a minute! No CA´s since I read your great article.

    Thanks a lot.
