Remove colour fringes

Counteract chromatic aberration in a click

1 Zoom in

Browse to our supplied start file, distortion_start. NEF. To identify problem colour fringes more clearly, select the Zoom tool from the View Tool section of the toolbar. Click to zoom in on the building’s sign. You can clearly see green and purple fringes clinging to the edges of the letters.

2 Correct Lateral aberration

Chromatic aberration occurs when varying wavelengths of light aren’t focused on the same part of the sensor. Lateral aberration is more noticeable at the edges of the frame. A click on the Lateral Color Aberration box is all it takes to banish this type of fringing.

3 Correct Axial aberration

Axial (or longitudinal) aberration refers to the appearance of blurred colours caused by a lens’s inability to focus on the same focal plane. A slider enables you to fine-tune the correction. There’s no noticeable axial aberration in this shot so we can leave that box unticked.
