Here's my 2 cents - If I render an image in Poser, I post in the Poser Gallery. If I render an image in Vue, I post it in the Vue Gallery. Do I post work? Yes, but not a lot, because I don't know photoshop that well and I don't know my tablet that well. HOWEVER, if I were to render an image in either Vue or Poser and then the BULK of it was Photoshopped, then I would post it in Mixed media or 2d. IMHO, as soon as you save your render to an image file, it's now a 2d image that reflects a 3D world.
