I'm going to be shooting an installed bit of glass art (a lot like this but a few feet wide by a few feet high. By "installed" I mean that we're not going for the floating-in-space product-shot look, but rather it will be on a livingroom wall. I have the luxury of a tripod and a totally static subject, so amount of light is not an issue, although direction and quality always are. I plan to bring a couple of strobes to gain some control over specular reflections.
