|Goal: to bring back the details of the cubs fur, that had goen lost in post processing.|
To do this i first added an unsharp mask to the whole picture. I chose the values Amount = 400% (that is a lot, you may want to use less), Radious = 0,5 Threshold = 0. However, i didn't want the whole picture to be sharpened, only the fur so i opened the "History window". I there clicked on the "open" state and the picture returned to the way it was before applying USM. I marked the USM state by the side, and then used the History brush to paint back the USM on the fur only.
Hope it is usefull.
