To my mind "Pure Poser" covers images rendered in Poser, the software that is used to make the models and textures doesn't matter, none of the original Poser figures were made in Poser, of course. "Almost Pure Poser" would be something that could be rendered in Poser (that is, all the parts could exist in Poser) but was rendered in something else, perhaps to get real reflections or better shadows. "Less Pure Poser" would be Poser items rendered in another programs with the other program also used to create the surronding area, the classic example is a Poser/Bryce combo, like my recent "Battery Bee vs the Pink Pony". At the other end of the spectrum we would have "Poser Paintings", the Poser image used as a underlay for a computer painting, which may have been the original intent for Poser 1. And of course there are various gaduations between all of the above
