Good weather this morning, so we did some bubble popping. I didn’t get much depth of field (f/2.8) from ISO 400, but what was in focus was nice and clear. You can see through the bubble, to see that the back of the bubble has popped. This is because Sarah’s hand was to the back more than to the side. That’s probably why the reflection is so clear: there’s no reflections from the back (because there is no back!!!!). Now I think about it, this is something of a one-off!
