Back in 2005 when I started with digital photography, one of the things that other folks always mentioned is that when an image is over-sharpened, it shows a halo effect around the edges. This halo is apparent in your osprey picture. Having looked at the video in this link

I guess it's sometimes too simplistic to talk about an image being over-sharpened. It may actually be a case where the sharpening is appropriate, but Radius or Threshold settings may be out of balance.

I've been hyper-sensitive to sharpening halos in my own images ever since. They tend to be especially obvious in images like this where there is a strong contrast between the bird's wing edges and the sky.

Thanks Koos. I appreciate this link. I or Topaz DeNoise AI seem to over sharpen on occasion.

To complicate matters this shot had a sky replacement so the haloes are not necessarily due to sharpening.
