Shot on clear glass with black seamless taped underneath. set on a 12" diameter concrete form tube lined with silver pleather. A small access hole in the side lets me put a 580EX on a small boom arm inside pointing down.
Small, shaped hole cut in the seamless lets the light up into the seashell. A second 580EX gelled blue and dialed in to taste was set camera left and aimed to feather across side and front and dialed in just enough to give it some sense of depth.
