Someone here posted some amazing pictures of an evening scene, with lichen in the foreground lit by an ultraviolet torch. Forgive me, I didn't note who it was, but if you see this, please say so we can thank you.
Inspired, as we have so much lichen in these parts, we bought a small torch. Last evening was it first test, and it was fascinating. Look at that insignificant patch at the top of the pic
Here's natural light vs UV. We're going to have fun with this
