Yes. I found your post on getting rid of sharpening halos very helpful. I used it on the shearwater above and also (with the opacity reduced to 50%) for darkening the white artefects I mentioned.Yes, I do the same, I choose the Low Light setting most often as it seems to sharpen the least but what Low Light does is give very ugly edge artifacts, not unlike chromatic aberrations. But I clean those up later and then the end result is pretty decent.
