These are Desert Rose seeds, just coming out of their seed pod, to be soon picked up by the wind in their effort to propagate new plants elsewhere. Another one of Nature’s amazing design achievements!
My settings were ISO 200, f/5.6, 1/360 sec at 59mm (18-135mm). My husband is holding a black foam board behind it. It was actually fairly breezy and we were afraid they would fly off at any time, but they remained long enough to get a few shots in.
