Sometimes the chromatic aberration created by the lens can cause a slight outline like that at high contrast transitions but it usually has a purplish or greenish color and it's not that wide. I'm not sure exactly what that is.
I thought of that. I tried adjusting for chromatic aberration but it made no difference what-so-ever.

Two reasons for having that white border around the edge of the rock, over sharpening or a reflection of the sun over the edge of the subject which is not unusual with backlighted photography.
It has happened to me with many of my backlights and others believed that I oversharpened the file.
Well, no definitive conclusion as to what caused this yet. Photographer states minimum increase in in-camera contrast and lots of clouds that day so not sure sun played that much of a part in this or not.
Worth remembering though.

Will check that out.
Person who took the photo is just now telling me she shoots JPG so, you could be right.
Thank you!
the solution is to shoot raw + JPEG. And if this shows up he can process the raw himself and eliminate the artifact.

Not a clue ... you don't know what chromatic aberration is. It is not a halo. Aberration would appear thought out the frame. You're not going to find an answer because, you don't understand photography or light. It is not sharpening but a natural digital phenomena due to light, light direction a clash with shadows. It can be avoided with a different angle/perspective and it can be corrected (see previous post). BUT no matter. This is like talking wall.

You are quite the a-hole, aren't you?
You claim to be a College Professor... well, your attitude and comments CLEARLY identify what is wrong with our educational system today!
I never called this a halo. I never called this chromatic aberration so why don't you go after those that may have?
You have clearly identified yourself as a very immature, whiney little a-hole.
I wanted to ignore you but you insist on proving you are very childish and you definitely need to go to your room for some "time-out".
I'll bet you pout when you don't get your own way as is evident here with your temper tantrum.
Go away!

looks as though someone sharpened or added contrast to the image.
I totally agree, this is simply too much sharpening.

This condescending remark is way out of line.
A natural digital phenomena due to light? Can you elaborate on that? Chromatic aberration is caused by lens dispersion.

I have never owned a Nikon so, I can't say anything negative about that brand. My comment was a joke and I think it hilarious that people get so defensive over such trivial comments - as if I attacked your mother.
Think about it... I realize you don't know me but, does it make sense that if I were anti-Nikon, would I try to help someone who had a problem with theirs?
So you intended it as humor but you think that is funny when people reply "defensively? But then that is the very definition of what a trolls do. They post inflammatory statements to get people to respond.
So if it was unintentional on your part, I am sorry for the barbed reply. (However if you intended to provoke defensive responses I am not sorry.) There are many trolls out there who try to start wars by invoking brands, etc, unnecessarily and they ruin otherwise good threads. For future reference, it is probably best to leave brands out of the post if you are attempting humor.
Mark and Boo.. let it go. Let's get back to the topic. It's rather interesting.

Whats interesting, we gave the OP his answer on page 1.

And the OP said he would check into that... and thanked you for the response.
At this time, the person with the problem has to make the changes, reshoot the scene and provide feedback. They have not yet done that.
I was going to say it's (CA) or chromatic aberration. It would help if you posted the entire picture and clicking on the store original button as well as the cropped image, and again alway click on the store original button. If you do that, then we could easily see if it's correctable with the CA correction tools in Photoshop or Lightroom.

A revolutionary idea! Thank you! :thumbup:
