If you look at this image here you can see how the edges of the statue look like they've been drawn around. This is how the image came out of the camera, from a not so good smartphone camera.

I'm just wondering if there are any techniques/plugins that can assist remove these over delineated edges without a manual brush approach ?

  • Yeah excessive sharpening applied by the camera software not the camera itself. Im a bit unsure how one would run a negative unsharp mask in photoshop but it would certainly be possible to build. Maybe its enough to just invert the highpass filter?

  • I had a bit of a go with frequency separation, then luminosity blur, but it was a bit of a faff & not entirely convincing.

  • See the discontinuity of the vertical edge of the statue and partially vanished wires in the sky i.stack.imgur.com/8MLhD.png I have never seen automatically made edits this bad, but I have made them manually in Photoshop and other programs numerous times and also succeeded to delete the original.

If it happens that you do not have a better version of the photo and the black edge must be taken off you can simply delete it. The next method works in this high contrast case.

  1. make a selection which covers the statue and its black edge. You get it easily in this case with the Quick selection tool. Select the sky and invert the selection.

  2. Copy and paste the selected area to a new layer. Apply 2 px Gaussian Blur to the selection in the background layer. It blurs the statue and its black edge to something less offensive:

  1. Invert the selection. Expand it 2px (=Select > Modify > Expand) and delete the edge of the copied statue:

The edge is replaced by the blurred edge+statue and it can still be seen but it's not as easily noticeable.

A more manual fix is to make the same selection (=the statue+the edge stroke) and drag the color outwards against the selection border with clone brush.

Even more easy is to select the sky, expand the selection 2px and drag with smudge brush the sky over the black stroke. It's done partially in the next example:

enter image description here

The lower half has cleaned edge.

I guess these options are not wanted in the question, but just in this case it would be about one minute job to do the sky stretching over the edge with the smudge brush.
