To tell the truth, I read NOTHING of the article associated with the post. It did not interest me. My only point to you guys is that the photo has numerous characteristics and artifacts that make it blatantly apparent.
MY level of expertise in graphic arts, photo interpretation and manipulation will remain a secret to you because you have no need to know.
Like I said before, believe what you want to. You will anyway.
I would like to see you try. Why don't you illustrate some of the "problems" for us here. Please don't waste our time with your perfectly straight edge "interpretation", that one's been debunked at least twice now.
I love it when people are "experts".
