My mother used to collect driftwood, sand it down and varnish it. There were really nice pieces some of which are still displayed in places. This was a small piece she kept at home. It always made us think of a small creature looking over it's shoulder. I have since inherited it. Over the years I made a few attempts at photographing it and this was the best. The glass ball is a real Japanese float that broke away from a fish net and drifted across the ocean where my uncle picked it up off a beach near Seaside, Oregon.
This is with the 100mm lens at 1/30th sec f16 iso 400. The camera was on a tripod. I had a white product backdrop on the table and taped to the wall. I shot with one flash directly overhead behind a large diffuser. Pretty much the same as the orange.
