I came across a fascinating photo of black-eyed Susans taken with a camera that detects only UV light. It was in a Scientific American article (July 2006) about bird vision, which includes the ultraviolet range. We humans are missing out on full flower beauty! Inspired, I googled the topic and found the following: Flowers in Ultra-Violet http://www.naturfotograf.com/UV_flowers_list.html Perhaps Daniel has already addressed this topic ... if he did and you missed it, go to the above to see the true beauty of what we view as a common yellow evening primrose (as well as other species).
I guess I missed that BPotD. Neat slide. I love "magic lantern slides" (that's how I know them), and like to make them ... convert to grayscale in photoshop, and then tint away.
