Thanks a lot.
I use a Panasonic Lumix DMC-TZ3, nothing fancy. For that shot, I darkened the room (I think it was at night, so I simply turned off the lights) and used a desk lamp shining from below. It's already been two years since I took that pic, but the image properties tell me it had an ISO of 100, and a shutter speed of 1/8 second.
I don't know a lot about the technical aspects of photography, but I usually have my ISO on auto, and vary the shutter speed (my camera only has 4 options, 1/8, 1/4, 1/2 and 1 second) until I get the result I want, and depending on the light I'm using.
Hope this was helpful.
