Best fast link from search engine about PBR:

In povray terms, it would mean: respect the reality, do not cheat even
if it is harder to model and might disappoint you.
It might mean staying away of HDR map (instead, you provide the whole

Lights are only placed where there is a real apparatus to provide lights
