Author's Note: Ok, this one is actually a photograph of some nice little hex detergent bubbles with my brand new macro lens!
This one was created by filling the bottom of a square vase with detergent, and then filling it water so that it foamed up nicely. A yellow piece of paper was then placed behind the vase, with a studio light shining through the paper and bubbles.
Take one macro lens and a teleconverter and... tah-dah!
Please view full for uncompressed hexy goodness :-D
