A Steve Ku creation. The 40DD - runs on a 10180, has QTC, and 2 trits. . . I believe he will be doing more runs of this light. . . you can check it out in the Marketplace.
Try a camera setting of ISO 200, set the aperture at f/16 and expose for 90 seconds.
Sometime before the 90 seconds is up flick the room lights on for one second and immediately turn them off, this lights up body details while not washing out the trits. If you always shoot at the same ISO setting and the same f/stop the only variable is time, which is easy to experiment with.
