White fringe on photo

[StuD]

Hi,

This has been bothering me for a while. Can anyone tell me what causes the white fringe around the clock tower on this photo? I have reduced it slightly using the Chromatic Aberation options in Lightroom, is that the correct method for sorting this?

Also, if there is any advice on how I could correct this further in Lightroom / Photoshop that would be gratefully received.

Thanks in advance.

Fringing like that is usually a sign of over-sharpening - but this looks very regular as though it's a halo left by an unfeathered mask used to manipulate or replace the sky perhaps?

To get rid of it is a pretty laborious hand retouching job.

Now you mention masking the sky, when I converted to grayscale in Lightroom, I darkened the blues quite a bit to get a more dramatic sky. I think that has answered it. Thanks for your help CT.

I should have also mentioned it's just a small section of a much larger photo, and I cropped this section out as it highlighted the problem the most.

Looks like a dodgy cutout with a circular grad replacing the original background to me :shrug:

nobody's ever gonna know with details like its a million percent crop and I've faffed with it in potatoeshop missing from the opener.
lets have a look at an unmolested full photo..

As I said in my earlier post, it was caused by darkening the blues when converting to grayscale in lightroom! Question answered, thanks!

I've overlayed a blue gradient layer with multiply and not had this kind of fringing, if that helps.
