Quote - Which is why renderers like Maxwell render in spectra instead of RGB (part of the reason for their ridiculous levels of photorealism)

I understand all the theoretical advantages behind spectral rendering, but so far I haven't found any side-by-side comparison of spectral vs RGB rendering that would show a visible difference. Would love to see one if anyone can find one :)

 

The closest I've seen is http://www.anyhere.com/gward/papers/egwr02/img/ColorPlate.jpg where the difference is measurable, but barely visible in the direct comparison and would go unnoticed without a reference.
