Thanks all, for the positive comments!
Also, a little follow-up seems to be due:
1. After using lights of 2 different colors--white and yellow(standard)--I found it best using the white lights, they're called "daylight" bulbs. I've tried using both the colors, after hearing that mixing the 2 makes it look natural. However, I wasn't a huge fan of having a rather yellowish orange tone on the pictures. I'd much prefer the white light.
2. The best was having only the lights coming through the "windows", especially when you have other lights coming in from the opening. Say, if you're working in a room, turn all the lights off, like your room, except for the lights that go into the box. This minimizes the light bulbs reflecting on your crystal.
I'll post pics when I have more time.
Thanks!
