hehe, that's my secret....I didn't make it myself. I got it from debevec.org. I am curretnly making some panoramas myself with a tripod, camera and complicated software noone understands except for it's creator. I placed the lights carefully, made the background object one-sided blablabla. I am planning on putting a marketplace item on renderosity as soon as the other 15 or so lightsets are done. Try before you buy.
