These are done with 2 to 3 images taken without moving the camera then they are joined together in post production.  Shot one has you as the painter, something simple with an apron.  Shot 2 we have you dress as you would on a relaxed day at the house or in some other drab attire.  Shot three you will dress the opposite, this could be a fancy dress, a cosplay, or some other dramatically different look.  You then get to choose, which is the reality in front of the painter, and which the painter is 'visioning'.
