This shot was aslo made with the old point and shoot cam, manual focus and custom white balance. This was taken only as a reference to the design. Note how "everything" reflects on the highly polished metal..from the red backdrop to exaggeration of "shadows" on the lower part of the ring band. That is a problem in many shots. Maybe a very uniform universal lighting with a point source for the stone will work..shall try to set that up. I am trying to avoid too much postwork..eventhough that is how it is done in advertising images.
