The intention behind this week’s challenge was to photograph long, swirling trails of smoke or steam. I…didn’t do that, and, instead, ended up with just a few photos that hew only very loosely to the theme.

First, a close up of frost—which is kind of like vapor? right?—on a leaf in my yard. Next, a side view of a gas burner on my stove. And, finally, a place for gas of another sort.

The first two I took with my camera, the second with my iPhone X.
