I am diving in deep about a technical problem today- chromatic aberration.

Chromatic aberration or color fringing is an optical problem caused by a lens’ ability to focus and bring together all the wavelengths of color on the same focal point.

Sounds super confusing, but in a nutshell it means that when you photograph a person (or especially small details) they lose their true color around the edges.

The lens cannot focus on all the color wavelengths and therefore gives the item or person a purple or green outline.

For example (above), you might not be able to see it in this picture, but look at the little boy’s hair and shoulders. There is a slight purple tint to his hair and the outline of his shirt. That is chromatic aberration.

Luckily, photo editing software like Lightroom can easily fix this problem.
Here are step-by-step instructions on how to remove it:

In Lightroom, click on develop module and then click on Lens Correction and then color.

Next, click inside the empty box that states chromatic aberration and move the color sliders up.

It will remove the chromatic aberration problem. Sometimes you need to zoom back out of the picture to see the full effect.

Final picture no more color fringing (or purple!)
