Lateral or transverse, chromatic aberration.
Lateral chromatic aberration, also called transverse chromatic aberration, is the blue-yellow or red-green fringing that can usually be automatically removed using the Remove Chromatic Aberration tickbox in Lightroom Classic.
Axial or longitudinal, chromatic aberration.
Axial chromatic aberration, also called longitudinal chromatic aberration, often occurs in images made with wide apertures (low f-stop numbers). It can be corrected using the Defringe sliders in Lightroom 4.1 and later.
Add chromatic aberration for a unique look.
Experiment with applying chromatic aberration on purpose to videos or photos in Adobe Photoshop, Premiere Pro or After Effects. You can take an image or film clip from average to artistic by playing with a bit of colour fringing or separating the Red, Green and Blue channels (RGB splitting). “Chromatic aberration could add a certain type of unsteadiness or psychological space within an image,” says Long.
