Nice job but I like the one in the example window with shadows.

Floating a piece of glass like this is tough (unless you ChromaKey it).

Shapes and colors really need a reference as they're solid object. Of course you don't want to just make catalog shots either!

I collect glass of this type and have at various times played with photographing pieces of it (not very often satifactorily I'll admit) and it is hard to convey all that light!

You can shoot on a turntable so you don't have to move your lights. After creating that well lighted background (transmitted light works soooo much better for glass) then you can play with angles by just moving the turntable and raising and lower the old tripod.

This is well done color and clarity. Thanks and look forward to more.
