An earlier test render that used radiosity instead of a light dome. The light
dome gives much better and faster results for the HDR probe (but radiosity
could still be used usefully for inter-object illumination - Tek posted a scene
that mixed light domes and radiosity a year or more ago from memory).

The row of spheres on the left is a mirror finish, the second row is mildly
blurred (with dents as well), and the right row has a stronger blur (and deeper
dents). The floor is a blurry reflector as well.

The depth of field obviously needs more samples to hide the checkerboard moire.

Cheers,
Edouard.
