Okey, let's begin retouch this photo

First, select bad area

Duplicate document, then arrange them as Title Vertically mode ( Windows >> Arrange >> Title Vertically )

Bring bad area to new layer by pressing Ctrl + J , change mode to Color ( on first document only )

Press Ctrl + I to invert color ( important step )

now, stand on every 3 channel, change Opacity parameter to bring bad area have same color with good photo ( only black, white and gray )

Stand on RED Channel

on 33% opacity , the bad area have same color with good area

press Ctrl + A to select All, then Ctrl + Shift + C to Copy Merged , go to right document, press Ctrl + V ( dual document, must stand on RED Channel )
