[VIS, UV] mating frogs in UV

While I was shooting flowers at Herrmanshof, Weinheim park, two frogs were sitting at the rim of a beautiful pond, very noticing my approac but patiently waiting till I was done with my shots - a very intimate moment between human and animal!

[VIS, UV] Helianthus: new vs old flower made visible using ultraviolet light

While I was shooting flowers at Herrmanshof, Weinheim park, I noticed that in UV the ageing of a flower can be easily detected, wheras in visible light, they look alike.

These yellow Helianthus tuberosus flowers on teh left side, clearly show age differences: top is in male stage (early), bottom is in female stage (late) but in UV things get much clearer! So I'm sure our beesies knew that way before us...

[VIS, UV] a first 340nm UV pattern?

Today while I was shooting flowers at Herrmanshof, Weinheim park, for the first time I noticed some "green" UV reflectance pattern, that according to my standardized false UV palette looks like a 340nm reflection. Unfortunately it is unsharp, but I will try and re-shoot it later...

I wonder if I may get that flower and make some spectrometric reflection tests...

[VIS, UV] Rudbeckia variants with nice UV patterns

Today while I was shooting flowers at Herrmanshof, Weinheim park, I found some nice Rudbeckia spec) which I haven't seen before, sporting some interesting UV patterns.

and here one with hardly has any pattern:


I have much to show from that session later...
