Purple fringing in the railing/branches - still chromatic aberration, or is this something else?

I am using sigmoid. DT5, but 4.x was the same.
I have tried cranking the chromatic aberration module way up, but its not really hitting it at all.

There is an old module called defringe which tackles your image easily.

Or the newer recommended chromatic aberration module will also do the job with a few tweaks.

And if all else fails then a localised mask in either color zones or color equalizer module could be used to desaturate the offending fringe color.

That is the three different approaches I would consider for troublesome images.

The moment i clicked “very large chromatic aberration”, the result jumped into what I was looking for. One of those checkboxes that just slipped past my attention.
I did not realize there would be a histogram once I enabled the the color zones piece. And now I start looking into that spike. Seems like a great alternative if I decide to disagree with the chromatic module.

I tried it with a quite warm setting

Well…thanks a lot. Now mine is junk.
Your sky so much better than i would have thought possible. But as I go through your .xmp, turning modules on and off to see what magic setting you used, it seems to be a combination of several. No easy button. Crap. I can sort of see what you did, but I cannot see how you looked at the image and said “oh, ill do this, this, and this!”.

Anyways – the way you handled the sky looks amazing.
Thank you for sharing.

For the sky the main components are haze removal and local contrast. But yes you are right it’s a combination of different modules.
