It is something that has always intrigued me but I never got it figured out. How do people shoot photos of items in such a way that it has no shadows, and you don't even see the product resting on a desk or any surface? The end result is just like as if the item is floating in a white void. How is that accomplished? Surely if they placed the item on something during the shoot the background would still have appeared in the final photo in some form?
