I'd been thinking of taking some HDR shots of studio lights so I could include
them in renders, but then I found someone who had already done it -
http://oliverwolfson.com/studio-light-hdr-images/
Here's a very quick example using pure radiosity (trying out importance sampling
too).
Cheers,
Edouard.

And a ball to show the reflections.

Looks very good. I think I recognize that model.
Recently there were some similar ones added to the sibl archives under
lightsmith (http://www.hdrlabs.com/sibl/archive.html)

I hadn't looked at the sIBL stuff in a while, thanks for reminding me about it.
As for the Lightsmith images, the first two are the same as above; the ones by
Oliver Wolfson. I think the difference is that they've been mapped onto meshes.
For POV I just used CSG and the image mask on Oliver's website.
Cheers,
Edouard.

Question about use of HDRI and reflection mapping...how does one get the
positioning come out correctly so that shadows fall on the 'ground' of
the surrounding image, and the object itself appears to sit on the same?

First I start with the image on a smaller sphere at origin. Map out
where the bright spots and points of interest are ... Use an even
smaller set of spheres (think of them as pins on a map) and transform
them around the image sphere. Works best with camera at -z ... that way
x is up and down and y is left and right.
