A few weeks ago I'd gone out out after work to catch some IR cloud images at a nature preserve, I was first puzzled by the little brown spot that suddenly showed in the greenery, and then thrilled when the two of these wandered out of the shubs and into the water to swim across the river.
I quickly grabbed the other camera (non IR with the zoom on it) and started snapping away. Truth be told though I was so going "oh wow, how beautiful they are" I'm surprised that the images came out as well as they did.
