I pretty much agree with Cynlee in the first post to answer. As for use of 2d and 3d stuff, likely I will say no....unless the image is predominately and I do mean predominately a PHOT0. I have posted images with lots of post work including ones made of a layer or two but it is obvious the initial and final work is essentially photography. Sure, this is line to cross and I can't say where. I wouldn't want all such manipulations left out totally. I don't want a poser figure in the foreground with a background photo, submissive and supportive of the 3d work while the photo is only decoration: That belongs somewhere else. Whew... For many, the computer is the darkroom and that is acceptable even with its range beyond burn and dodge and tricks done under the red light. Still, let the photo be the true and recognizable basis of the image. I may recant tomorrow..first shots at this topic.
