The black & white versions work very well. Particularly the Reception area.
It's interesting, just on the subject of realism alone, I've always noticed that a CG image will typically look instantly more realistic when modified to remove colour. This is without any other tweaking with filters to try and achieve a photographic look - adding grain etc.
I wonder why that is typically the case.
- Is it because of a tendency for the user to make mistakes in the colour values they input into shaders (unrealistic saturation amounts in diffuse)?
- Or are there some subtle shortcomings common to the render engines in the GI and the way colour is transferred compared to value? Or maybe something in CG noise when read in colour compared to B&W.
Probably much more likely to be the former (user mistakes), I suppose.
Anyway, sorry to sidetrack. It's just I've always been curious about that and it seemed like a good place to mention it given you were comparing versions side by side.
