So this time the target was a nice Rudbeckia flower which is known to sport some otherwise invible sharp UV pattern. The macro lens used was a calibrated 130mm lens.
As light source a 375nm UV LED was used here and no other modifications were done, not even a filter was used.
The second shot I used a filtered 365nm UV LED, also no lens filter and the colors were somewhat adjusted to taste.
So I would say, that there is quite some potential in these UV sources and thus will be studied further.
Stay tuned, more will follow on that fascinating subject...
