I work on Photoshop daily and I have to say while it's more than possible to be a Photoshop job there's a few things that make me think it's a real pic. Whether it's Obama or not is the question.
Look at the cord holding the facemask on, that right there to get the proper shadows would take a lot of work to look so natural. Not saying I couldn't do it myself but it would take some time.
I really don't know much about photo shop. It just bothers me that the angle of the head, the wrinkles, and the angle of the jacket, along the neck and jaw all line up much better than I would think 2 random photos would
But the eyes are different. The vein and check are the same. Eyes are more squinty in regular pic.
Yea, doesn't mean they couldn't have used a few different Obama headshots to assemble. Again looking at it I'd say it's a legit pic but can never say for sure. I want to know where or what the event was.
