I need test more this setting because according to G. physic theory, amount of bounce lights should be at least 50 (!).
He told me that big amount of bounce light is normal and diffuse model should be adjusted to it.
For example white and flat wall in real World has white color but not pure white...is light gray so color should be around 210.210.210 and diffuse maximum 90.
White concrete material diffuse according to physics is very low: 50-60 %, etc, etc.
With correct diffuse and big amount of bounce lights (at least 40) we should receive correct render. Also we should not be worry about colors because low material diffuse consume a lot Photons power and final bounce light is much lower.
Small amount of bounce lights create errors in corners (10 bounce lights):

Effect should look that (Path Tracing 10 bounce lights):

....and this is also
incorrect (!)...is correct with sampling but not correct with Global Illumination.
That`s why in RC3 we have some new tools for that and alert about low ratio photons.
The resolution of GI in Photon Mapping also is not so important like we thought. It can be 300 mm - more important is saturation by photons not to lose continuum of precache.
