This result isn't too bad. Its not that great either, there's still a lot of reflections all over the place. I used one strobe with a reflector umbrella bouncing off the wall to the right. I think for ideal conditions here's what I would want:
- One softbox at the right with a reflector on the left. The softbox should give nice diffuse lighting and a key light on the bottle while the reflector should provide adequate fill for the front of the bottle and glass
- A backdrop and sides to get rid of errant reflections
Technical Specs: Canon 1D3, 85L, f/4, 1/4s, ISO 400, strobes fired.
