Tiny Tuesday: Tiny Rainbows

I'm not sure whether this really qualifies for Tiny Tuesday but I'm posting it anyway (and many thanks to Carol Dunham for hosting this month).

As I walked home from the Metro station in the dark this evening, my glasses were all misted up after I'd been wearing the obligatory mask on the train - and I noticed rather beautiful little rainbows round car headlights. I wondered if I could simulate the effect in a photo. So I went out with my camera and blew on the lens to make it mist up like my glasses had been: the effect wasn't as pretty or dramatic as I'd hoped but I thought it made for an interesting blip anyway. This is almost straight out of camera - with just a bit of denoise and increase in saturation.
