Can't Remove Purple Banding/Abberation In Image

Question

Hello Adobe Community,

I have this studio editorial image and surrounding the subject is purple/magenta banding/chromatic abberation. It's not that noticeable on my laptop/in photoshop but it is very noticeable on Instagram. I've tried editing in 16 bit then converting to 8 bit etc. I've tried image>adjuststments>hue/sat and turned down Magenta/purple. I can get rid of it by turning the whole image temperature warmer but it is pivotal for this project to be a cooler toned image, unfortunately the purple banding still shows up. Does anyone know how to remove/fix this?YINFINAL.jpgIMG_0542.jpg

This looks like jpg compression artifacts, caused by using a too low quality setting when creating the jpg.

You might not be able to eliminate it entirely, but using a high quality setting (like 85 in ACR or Lightroom) should produce better results. If you export from Photoshop, quality 6 is probably about the same as 85 in ACR/Lightroom.

I sometimes see similar artifacts in skies at 85 quality – jpg compression is destructive, even at high quality settings.
