I found this similar question but it is about finding hints in the *digital file* :[how-to-identify-photoshop-edited-files](http://photo.stackexchange.com/questions/26170/how-to-identify-photoshop-edited-files). I want to know if there is a way to do this without looking at the digital file, for example If I only have a print of that photo available. What markers should I look out for in a photo, to indicate a photo has been edited or tampered with? Note that I do not have *any* experience of photography. This is just a question out of curiosity!
