This is from the afternoon Ctein and I spent running around after Fourth Street Fantasy Convention, mostly playing with his IR-converted Olympus EP-1.
I fairly often see the rainbow down in Minnehaha falls. I haven’t had much luck photographing it, and this version isn’t going to go anywhere beyond my blog that I can see (I’ve already used pretty much all the tricks I know to bring the rainbow out in the image).  But it’s kind of nice, still.
