concentrating light

This time I have to concentrate the light on just part of the scene, so using one studio light a black reflector and some pieces of amber jewellery I set to work to see what I could create, I laid the amber on a black cloth then set the light up minus any diffuser and then set the reflector so that it sat covering first about a quarter of the light then about half of it, I used a shutter speed of 125's (this is the fastest speed I can use to trigger my lights) and an f stop of f5.6 iso 100 flash white balance and set to work photographing.

I like the second of the shots best this was with half the light covered so the band and part of the large piece of amber (this bit isn't real unfortunately)! were in shadow and the light is concentrated on the centre part showing the small pieces up better.
