A relatively cheap way to get “aerial” food shots, here is a hybrid dolly, with some extra risers, a long 3'offset, an original slider, oconnor 2575 and the camera, turned upside down.
The lens was a wide-angle macro (24 or 32mm) which provided great depth while tracking in over the pizza.
I believe the stop was around 5.6-8 to provide some depth of field.
