Hi Helbredth.....
One possible option woul dbe to use the "Color Range" function.
Since the chromatic aberation in red is made up of a few mix of colours which are sort of distinctive, in some cases you may use the following method....may and may not be liked by some but its another tool to learn.....
...
1- Open the image to be edited
2- Go to Select->Color Range.....
3- Use the eye drop icon to hover in the area or colur that is at the edge.....
4- You can adjust the FUZZINESS of the selection to select different size or should i say "broadness" of your selection.
5- Once selected.....you can go to the Image->Adjustment->Hue/Saturation
6- Adjust the selected region to fit the background....
7- Repeat Step 3 to 7 as needed depending on the colour spectrum in that aberation....
8- Here is result i got in a quick edit...its abit patchy i think due to the resolution if the files....
THis method could be used with all the other methods mentioned above by the other CS members to achieve your needs......
regards,
me
