Thanks Greg,

I ended up ordering a hollow 7.82 inch diameter polished steel garden
"gazing globe" made by blomus. [65067 Polished Garden Globe, 20cm].

In searching, i found these other sites, which may be of interest to the list:

I have a rather heavy steel ball-bearing I purchased some years ago. It worked great for a while, then got scratched and rusted. I've heard from Paul that there are some silver juggling balls that work quite well. I think there's information on where to get them on his website.

Cheers,

Dear HDRI list,

After viewing Paul Debevec's Rendering With Natural Light Sources:
http://www.pauldebevec.com/RNL/Source/

I have become interested in acquiring a light probe to enable
image-based lighting in my Radiance work.

I would appreciate any suggestions for good sources (+ details) for
ordering suitable chrome (or other) spheres.

I've heard everything from Christmas ornaments to solid steel
(polished) ball bearing work. Anyone particularly satisfied with
their sphere?

Thanks!

-Kyle

Hi Kyle,

Some years ago I also ordered such a garden ornament from the US for this purpose. Found it to be too geometrically imperfect. Not spherical enough and, resulting in wobbly environment maps. I now use a 2 inch polished ball bearing ball I got from a hardware store.

But, the number one method for high quality environment maps is to use the fish eye lens and stich a full sphere from multiple viewing directions.

I have always used HDRShop for this but now they don't offer version 1.0 for free anymore :frowning:
