Subject is wearing red and black plaid shirt. It appears that there is a gray semi-transparent spill in one location, but then it it smeared across other areas of shirt. Don't know how to remove it using the color replacement brush, because of the plaid pattern. Pattern of course changes color where highlight and shadow hit it.
I have PS CS5 with iMac running OS 10.6.8
