EDIT: This lies part of the challenge of getting the light/s, reflectors and camera position "just right". I lost the tip in the above shot. Went back and -slightly- shifted the camera position and adjusted the reflector a bit. Tip was good. Then thinking I duplicated the set, I broke it down and went to post. Yeah the tip was nice but now that reflection that ran up the handle wasn't the same length. Then noticed that the dark handle wasn't separated from the sake bottle so they kind of blend in. If I shifted the bottle so that the light area was there I'd have some better separation. The eyeballs were tired so will have to make a another go next time. LOL... I can understand why doing a composite makes sense for these situations. Amazing what a slight camera shift can do.
