The focus of my bubble experiments shifted from trying to capture the patterns of three
dimensional volumes created through touching soap bubbles to capturing their
interference patterns, the colorful iridescent swirling patterns. They’re awesome to watch,
although rather short lived, and are quite fun to play with – the kid in you will love it!.

Here’s a good source for various bubble solution recipes if interested:

Lighting played a critical role in capturing these interference patterns and after some
experimentation I found that spreading the light works best rather than a single source.
Below is the setup used for these last two shots, Interference 825 and 938.
