Oh man, this is going to be hard. Interior renders are perhaps the most convincing CG renders these days IMO (ever since Vray came about, did you notice how many used it?
)...
OK, not quite as hard as I thought. 20/20 for me. Those fur things CG artists like to put in their archviz renders as if to say "Look, I can render fur!", they're so often a giveaway. Some were definitely challenging though. Mostly the telltale signs were material surfaces, or subtle lighting cues. In one case it was a camera artifact.
Interesting that none of the photos were actually staged furniture displays. The intro seemed to indicate they might be, but they were all people's apartments, heh.
I love seeing these things. I just wish someone were doing it with landscapes...
