I think it's very interesting that whenever a geek says a photo is digitally altered, Photoshopped, we all tend to believe then, presuming that their assertion based on some advanced technical analysis that we mere mortals couldn't understand.

We take it as fact when a Snopes or the reddit community calls an image Photoshopped. Why are we so enthralled to this new digital priesthood? And how indeed can we separate fact from fiction?
