*understood* but in situations such as this shot where it wasn't done right due to not being planned, and not knowing better... it would be nice to know how to fix a photo that turned out beautifully framed, but not quite perfect.
Pretty simple. I just copied the image into 4 identical layers:
2) Ground (because it is basically in the same focal plane)
3) Tree (because it is just outside the DOF limit I would have used)
4) Forest & water (because it is even further outside DOF limits & would have been thrown further out of focus)
Selected dog in layer 1 and ran a High Pass Filter & set blend mode to hard light. Slight curves adjustment.
No changes to ground layer.
Selected tree in layer 3 and applied slight GB (just a couple pixel's worth).
Selected forest & water & everything else that was far away in layer 4 and applied slightly stronger GB (still just a couple pixel's worth, but more than in layer 3)
Merged elements of all 4 layers.
Took about 5 minutes. Then created .gif to demonstrate how changing the emphasis can draw your attention to the subject, rather than the distracting surroundings.
