One of the websites for photo tips suggested black velvet. Second photo is black velvet.. while it really "pops" it does lack some detail.. I think in this case my lighting was too strong!
Here is another case, a pair of earrings in sterling and clear crystal. Again, it pops on the black, but the silver is too bright and lacks detail. Last photo is just the black.. the light background didn't turn out at all.
Let me know what you think!
