I’m sure you remember me complaining that lighting Glass is perhaps one of the trickier aspects of DIY product photography. The tendency to cause glare and reduce contrast if the light source is not correctly positioned is a huge pain. However, once you get the lighting right, Glass lets you come up with some really beautiful images. As can be seen in this post.
The following image was shot the same day using the same setup, but I used cups instead. You can see how they reflect light differently.

Setup (Shared with the original Glass shot):
I guess its not true that you need a pro studio setup to get interesting images.
