Chromatic Aberration is another effect to mimic real photos and gives the illusion of realism. It is famous for giving a sci-fi-ish look to the artwork.

The red and cyan ghosting effect on the edges are the result of Chromatic Aberration.

In Photoshop, this is done by resizing one of the RGB channel.

You can get channels for an image by the next way:
1)Create 3 copy of image layer
2)create 3 layers pure red, green and blue 255 0 0, 0 255 0, 0 0 255 RGB
3)set Multiply mode for RGB layers and merge it to 3 copy
4)set Add mode to 2 top layers


So you can little shift or resize any of Chanel-layers to get chromatic aberration

Thank you for the workaround! Do you perhaps know how to make a working script for these actions in the mean time? I am unsuccessful at making a script to repeat these actions. The script would jump around to other layers.

A script counts layers from below. So in this task, you can save and use script only for a single layer document (merged image) or with some special structure of layers.
