I havent seen the galery images or the comments, but here is my take on the issue. Photorealism in 3D work is used to describe an attempt at making something entirely computer generated look real. In painting, it is to do the same with paint (obviously). You can even combine the two and paint a 3D render for better realism. However, real pictures dont fit into the equation. Using real images to enhance the work defeats the whole purpose. So a picture rendered within Poser then composited with real pictures is not photorealism, it is a composite image.
