yes you might be right - it was confusing me, that the camera post-processing isn't overriding that "white balancing" in physical camera, maybe i should have turned on Tone-Mapping in camera modifyer.
About corona camera - i kind of stuck to using standard max physical camera to have it interchangeable with Vray - not sure yet, if Vray can handle Corona-Camera or vice-versa.
