Here today shots of the attractive Oregano - Origanum sp. nice smelling spring flower which also is a wonderful cooking herb, not just for pizza. Shots were done aside from visible photography in reflected ultraviolet using Baader-U and the deeper reaching Jupiter-U filter, as well as in simulated bee vision using my XBV filter. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

UV image using Baader-U filter (approx. 320-395nm, effective peak approx. 375nm):
UV image using Jupiter-U filter (approx. 280-385nm, effective peak approx. 365nm):
Simulated bee vision image using experimental XBV filter:
Quadriptych of the above images:
This Oregano inflorescence has a UV pattern, its little petals reflect around 380nm when fresh and this disppears when the flower wilts, which shows especially well in the shorter wave Jupiter-U shot and all that gets nicely visible.
Stay tuned, more will follow on that fascinating subject...
