Freezing bubble
My first attempt at photographing frozen soap bubbles.
Most photos you see of this kind of thing are taken at around -15 degrees or colder.
The coldest it got on this morning was -4 (Celsius) and it doesn't get much colder than that here.
I'm no means an expert on the subject, but from what I could work out was that the air temp. wasn't cold enough to freeze my bubbles but instead they seemed to freeze from the contact point upwards, in this case a metal park bench (it looks that way in the photo anyway).
I think this is why I couldn't get full round bubbles to freeze on the grass.
Consequently, this makes completely different ice patterns on the bubble.
One advantage though... in minus 15 or colder, the bubbles freeze really fast whereas in minus 4 they were taking around 15 mins to get to this stage... which meant I had the time to take enough images for a focus stack without changes to the ice patterns.
Taken at Clare South Australia.
23 images handheld at 1x with the mpe65 lens and focus stacked using Zerene.
