Hi Greg,
I've had read both articles, and the text describing the process looks
doable. We use the same camera and have several flashes. Using 1 flash seems
better now, since I am not able to build the 3-flash controller (maybe
later). Mac is fine.
Anyway, I would be glad to try it,
A soda-water cheers,
Iebele

> Hallucination, I would like to experiment with the suggested procedure

> Depth Hallucination" says ''Once we have an albedo map and a depth map for
> our surface, virtually any rendering algorithm may be applied. We use the
> Radiance

> describe in more detail how albedo and depth maps can be achieved and used
