This car is about the size of a smart phone!

I used a black background in it. You can use a card table turned upside down and cover it with white bedsheets on three sides and the top. This will difuse the light. I use a halogen work light for the top about 2 feet away ( they get hot ) light and a halogen flood light on each side. The base it is sitting on is a piece of 1/8th inch sheetmetal painted black at a friends body shop.
I also think B & H sells them but they are smaller. They do have larger ones but they are costly. You can turn lights on or off to create shadows as well.

Nice.. Great idea too, if I want to shoot objects indoors like that this is locked in my memory bank.. Thanks..
