These shots were done using an extention tube, an UV Rodagon 60mm and a Baader UV/IR Cut filter to suppress the UV exciting light source (Nichia 365nm UV Led lamp/flash). Here the visible shot first. [as usual, a click on an image opens up a larger view]
And now how this flower looks like when radiated with UV light @365nm. The pollen shines bright in UV induced fluorescent yellowish white, whereas the petals emit some reddish and blueish colors. Especially the tips shine up very bright.
Now on to the reflected UV light image here. Not much reflectance to notice though, but a beautiful velvetish surface!
So I hope you enjoyed that journey to an Easter Daffodil with me!
Stay tuned, more will follow on that fascinating subject...
