Bubble trouble

I attempted yesterday to shoot soap bubbles. Some success, but I think what I really need is more light. I shot everything at f/32 for the greatest depth of field, but focusing was somewhat difficult due to the fact that the surface of the bubble is sometimes absolutely transparent, but not in the pictures depending on where the light source was. Not sure why the top edge of the bubble has multiple rings or edges, but I do like the colors that it captured. Also, I tried a few times to fire the flash multiple times, but the colors on the surface were constantly changing, swirling, etc., so one flash is about all I can get and still have a good image of what the colors are doing.

Your opinions and if you have tried this before, some advice.

Nicely done, the rings of Saturn?

I have not done this technique yet but it is on a to do list.
I think the images came out very well. Like #2 best; being full frame adds to overall appeal. Definitely abstract and an example of nature creating its own patterns. Good job.

I can see where this could be an addictive subject and pastime! My only question is regarding f/32. Most lenses experience diffraction above f/16 and are not as sharp. So you might read up on lens diffraction, but also experiment with wider aperture.

I hadn't thought about diffraction problems. I might try again sometime with something closer to f/16.
