After a couple of failed attempts with the mantlepiece clock, I decided to give this setup a go using an old watch without a strap.
It was shot on a sheet of black perspex with a black sheet as a backdrop to kill any reflections from the room. The watch is propped up with a piece of Blu Tac and the coins are free standing. I used a led video light to illuminate it, but couldn’t find a position for it that didn’t reflect on the glass. I finished up bouncing the light from a silver reflector on to it which made the scene pretty dim, hence the 2.5 second exposure. 2.5s f11 Iso64 using a 200mm macro lens.
