I love this picture but the halo around the rock structure in the background is so bad I wouldn't want print it.  It was taken with a D750 and Nikkor 24-120mm 1:4 G ED lens.  Post processing was needed for the photo but made the halo worse. 

 

What is the cause and does anyone have a recommendation on how to avoid this in the future?

To properly answer the question, Tim, I
would need to see the original RAW file!

I meant to mention that the camera was set on JPEG.  Earlier in the day I was experimenting with the HDR setting on the camera and forgot to switch back to RAW.  This picture was not taken in HDR.

Then, I guess recovering the highlights would possibly
not help much on a jpg even through adjustment layer.

I don't know if this will answer your question or not.

This looks like a combination of chromatic aberration and overly enthusiastic sharpening or contrast. See what happens if you start your post work with a CA removal tool. In hard light, you can reduce the CA by stopping down a bit.

 

As this was shot in jpg, what Picture Control did you use? Some of them apply far too much sharpening and contrast as standard.

As I got into this I found a mess.  Can't find the original, but I believe the first photo below is the original downloaded to my IPad.  I also realized the post processing was done on my IPad using Snapseed.  I use Snapseed while traveling to get a feel on what I can do with an image.  When I get home I'll normally do any PP in LR.  The second file is from today after PP with LR.  As you have see that halo is in both photos but not as pronounced.  I found when I went heavy with the  Presence vibrance and saturation  to bring out the colors in the rock and sand the blue in the halo grew.  I then only adjusted the saturation and luminance for yellow and orange.  I think this made it better but it still bothers me.  I did not do any sharpening in LR and tried the CA correction in LR but it did not help.

 

Fletch, Thanks for the link it was very helpful.

Merco, I think picture control was on landscape but I can't be sure.

 

I'm not normally this bad at controlling my images and files but I'll use the excuse that I was on vacation.  Without knowing how to trace my steps I certainly missed an opportunity to learn.

 

Thanks for the input

The last image looks pretty good to me but I see your frustration with the halo.

 

Confession; I am a bit of a beginner with Photoshop but I had a play with the first image on my machine using the clone stamp tool and a fairly fine brush, sampling in the clouds to redraw the outline of the most distant cliff. It would take a pretty steady hand and a fair bit of patience but I think it could yield a good result.

OK, I am the new guy, student in training ... but what I see in the first / original post at the top is awesome color in the mom and son and the design in the sweater is so vivid it makes me dizzy..

I do see the halo you speak of but the subjects jump out so I did not see anything else.
