It seems like whenever I use the adjustment brush in acr to lighten up an area I get very bad artifacting. Is this a known problem and if so hopefully will be improved in the future. My guess is I will have to select the area in photoshop and lighten the area. I always thought adjustments on the raw file are better because of being non destructive but I really have my doubts about the adjustment brush tool.
Here is the link to the photo at original size. I would like to make a 16x20 print out of this and my thinking is the quality will not be good.
