camera on a tripod close to the setup. 6" to 8" above table level should be good for most small items.
i have also used two more foam boards, scored on the back so they are self standing, to create sides to my "photo booth". this will provide neutral reflection for lights or shiny items.
set your item at a slight angle in the center of base foam board. don't put it too close to the background foam board.
make sure your item is as clean as you can get it and begin taking your shots. natural lighting is best. window or ambient light. never use an on camera flash for these type
