Etched Glass Lighting
Some experiments in lighting etched glass. This particular wine glass, a cheapo from Kohls, has a very simple etched pattern that looks ok until you look close, or feel it with your fingers. Research online indicated that bottom lighting was the key, but I found there has to be back lighting, and if possible, interior lighting.
Through the view finder, after polishing the glass, it looked fine. But some of the lighting situations brought out a huge number of internal flaws in the glass itself. At first I thought these were dust specks, but I double checked the cleaning it there was no dust on the glass. Well, I did notice one dust spot later in the shooting, probably because there was some dust in the room. Dust shows up as a dark spot, not a light spot.

A while back I'd bought a cheap wine glass with some nice etching on it. I cleaned and polished and had what I thought was a very clean glass and proceeded to try to capture the etched lines on it. When I used an overhead light, I discovered the reason why it was cheap: full of interior imperfections that my eye hadn't seen. Actually, I think most of the imperfections were microscopic pieces of lint from the towel I used for the final drying/polishing. I couldn't see them with my eye though.
