My favorite, a shot worthy of a large print. Thank you Klaus for sharing this, and many other fantastic views to the invisible World.

Well, I like the first shot best. If I was dropping acid I'd probably like the
others, too. Laughing Superb detail and bokeh, Klaus!

What is that green bright thing in the fluorescent image?

Some lint I guess. tried to gently brush it off but it did not go away. It certainly does not belong to the flower!

Very interesting! What's the difference between UV shot and fluorescent shot?

UV shots is REFLECTED UV light shot using a UV light transmissive filter (300-400nm), whereas Fluorescence shot uses a UV BLOCKING filter when at the same time the object is lit by UV light (UV stimulated emission of visible light)
