These won't change photographic history but they were challenging and fun to take.
very cool! I really like the subtlety of #2.
Looks like jewelry. Very nice.
Taz, Richard, thanks.
I really like the 2nd photo!
And I agree with Richard, these do look like jewelry.
Oooh, lovely Don. I, too am a fan on the second one. You said they were challenging to take - care to share your method? It's always good to learn.
Sara, glad to do so. It was jerry-rigged everything and I had two unsuccessful tries before I worked out the kinks. The light came from a room uplight placed under a coffee table with a glass top. I put sheets of colored plastic on the glass top. Then I put the clear plastic top of a seedling container over the plastic sheets and put a small bowl of bubble mix atop that. The seedling container was used solely to increase the distance between the bubbles and the colored plastic sheets below so that the colored plastic would be out of focus. I blew air into the bubble mix. I shot straight down at the bubbles with a 100mm macro lens using a tripod, moving the colored plastic around until I liked what I saw. There would obviously be many other ways to do this. I think you'd always have to backlight the bubbles somehow and control the light they're reflecting.
PS: I forgot to say that with the second one, I didn't like the color, so I converted it to black and white and toned it.
