Today about a Bidens ferulifolia flower, one of my fav UV "models" shot outside using sunlight. Shots were done in normal human vision, in UV using the Baader-U filter as well as in simulated bee vision using my various XBV filters respectively, that simulate insect / bee vision in just one shot.

This flower has a very prominent UV pattern (365nm peak) on its UV-bright petal tips, that's why I like it as a standard test target a lot.
Stay tuned, more will follow on that fascinating subject...
