IKEA flower

[Fandyus]

I recently visited the IKEA store in Dresden. When we were leaving, an employee handed each of us a flower for free, as IKEA is celebrating an anniversary. I was quite pleased by this, as the flowers look quite nice and seem to be a good target for my shennanigans.

Thanks! I actually tried UVIVF with my Nemo as well but didn't end up posting it as it looked very underwhelming unfortunately.

nice group

I am amazed by the mottling of the petals in the UV photo

That is typically caused by the surface cell structure of the flower rays. The "conical cells" (or sometimes other shapes) partly pass and partly reflect light so there is an iridescent effect. If you change the angle of the light hitting the petals, the iridescence shifts. That's how you prove it is an iridescent effect and not some by product of underlying pigments.

 

Penso che: questo è un effetto iridescente causato delle cells sulla superficie(?) della petals. Le cells curvano(?) la luce.
