Bru - Sounds like you need something like the cloud dome. These are used for product photography. They give excellent diffused light, stop hot spots from lights on metallic surfaces and take away the reflections. The link above goes to one of the companies that sells these. They're not cheap, but take a look at the before and after shots. Also, I would think you could build something out of white material that would do the same thing. Make a cube shaped frame out of something like wire or PVC to hold the material in place around the object your photographing. -=>Donald
