Camera: Canon PowerShot G6 point-and-shoot
Shutter speed: 1/50 (I thought it was higher, but that's what my EXIF data says)
I used a big ceramic bowl of water in a fairly dark room with a lamp to the side. The camera's built-in flash completed the exposure. I used an eye dropper and took several shots to get one that I liked. The colors come from the glaze of ceramic bowl being used.
