Thank you for sharing your image with us! It's far beyond my ability but I know
just enough to appreciate the work and talent that went into this image...

Have a great day!

Kind regards,
Dave Blandston

Thanks for the info,
Ouch for the file size... if you make two less than 10GB zips, you could upload
them to http://dl.free.fr/upload.html

I heard that Radiosity nearest count could be dropped to 1 with latest POV
versions, if you use POV 3.8 you can use AA method 3(stochastic) and use
minimum or 0 aa value leaving most of the smoothing work to a tiny camera depth
of field (aperture) value.

With these changes, Radisoity count can be lowered down to 100, and error_bound
moved up to 0.75


About Pretrace, I opted for using half of this for my default pretrace_start
(0.04), but I can't remember if it would give me render time improvement, or
faster readability of picture at very little cost. My default pretrace_end is
0.004

All this sounds like lowering quality, but animation quality is subconsciously
expected to be lower, not higher.

Norbert, I'd like permission to use your Light & Shadows image in a 
video for a Kickstarter I'm producing.  I tried your e-mail address but 
it bounces.

Please feel free to contact me at dav### [at] simberoncom.

Thanks,
David Buck

I'm really sorry about the delay,
you can use it in the video you are producing...
