There was a nice tutorial while googling for HDRI, basicly the idea is to 
take a mirror ball (regular ball of reflective silver metal or somthig) - 
it will reflect 180 degrees around. Now take a photo of it. Then take photo 
of the opposit side - and this images can be combined (using proper 
software) into one full 360.

Also, You must take not one pair, but severl pairs of images with different  
brightness settings - so that one image will show dark areas (while 
everythng alse would be totaly white), other will show light areas (leaving 
everything eldse almost pure-black), etc, their combined togeather create 
dymaic range image.
