An ideal radiosity scene.

Try it again. Don't forget to look at the rad_def.inc include file (part 
of the standard distribution). It's been greatly improved in quality and 
speed since the earliest versions.

High Dynamic Range Image. An image format that can store values outside 
of a 0-100% range. It doesn't necessarily give more realistic results in 
POV because color values used internally are unclipped anyway, but it 
allows you to use precalculated or real-world samples for distant 
surroundings.

Correct. However, the soft shadow can sometimes give an appearance 
similar to actual radiosity.
