It's cold out and I picked up a soldering iron a few weeks ago. I feel that fully explains how these photos came to be. More details in the links for the interested.





A behind the scenes setup shot. A roll of stiff white cardboard paper stuff made a light tunnel. To get the thin film interference on a soap film, you need to have your light source in the right place so it reflects on the surface of the film. This gets complicated when you have planes in a bunch of different directions. Just surrounding the entire model seemed simplest:

Nicely done - with both the soldering and the photos.

Beautiful! What would they look like if you take them out into the arctic cold for a bit?

Cheers! I'm not sure why I haven't tried soldering before, it's both practical and entertaining

Fragile, neat, but tough to light in a way that makes the textures pop. Freezing them was what I had planned from the get-go, but the thin-film interference liquid version was so vibrant and turned out well. I'd been photographing frozen soap films (example) with just a single plane and that's much easier though still a bit of a challenge (light placement is pretty finicky with even a single plane of feathery ice this thin). Here's one after it started to collapse, which was a little more interesting than the intact version.
