If you’re a stock photographer or just selling stuff on Ebay, you might want to take a look at the D-Flector, a portable studio backround on a briefcase. All you need to do is open the case and put it on the top of a desk with your product on it. When you take a picture with your digital camera and flash, the reflective background illuminates with the flash, giving you an ideal white background for your product. No need to buy those expensive lighting equipments or tabletop.
