    Find the exact difference between 2 layers

      I have a question:

       

      I have 2 photos, exact the same position, light, color etc. the only difference, in one of them is i.e. a person (the other one could be described as an empty background plate).

       

      what do I have to do to get a selection of what pixels are identical between the 2 photos, so I can invert that selection and can isolate the person?

       

      (the usual suspects, difference, subtract etc don't do the trick, converting both to a smart object and then going through the stack modes also doesn't result in anything that resembles a clean mask).
