BT-
No light box here. I tried one in the past, but with little luck. I got frustrated and went back to shooting natural light Maybe I'm just not patient enough... If I can find where I stashed it away, maybe I'll give it another go.
ASF-
I think I've managed to use that technique, but it leaves me limited in the kinds of shots I can take
No head-on direct shots... Unless the crystal is flat and the dial is white (or if the crystal has chief AR; good for modern sapphire pieces, but not so good for vintage Rolex)
