I was testing a ligting setup and it came out pretty good.

The model and image maps from hdri.cgtechniques.com/~sibenik2/
1 light source and ambient sky dome. save_data with error_bound 0.05
and final with error_bound 0.2.

Findings.

Clipped radiosity samples are only an annoyance. The 2nd image
demonstrates this effect when the scene is rendered directly to
display. I used sorcery to get nonclipped radiosity from std 3.5.

1600 samples isn't enough to gather smooth illumination from sources
with small solid angle.

Radiosity ignores brilliance finish parameter. Not that important
but would add that extra touch of realism.
