[UV] Cinquefoil or Potentilla flower: Baader-U vs Jupiter-U filter for reflected UV ultraviolet photography

Again more about that new Jupiter-U filter of mine. Also those shots were taken at the wonderfully blossoming Hermannshof, Weinheim, Germany. This time it is about a yellow Potentilla flower.

All triptychs are presented VIS left, Baader-U middle, Jupiter-U right:



Potentilla has a very strong UV reflection around 365nm, so much that it actually overpowers all around.

Stay tuned, more will follow on that fascinating subject...

[UV] bog-bean flower Menyanthes trifoliata: Baader-U vs Jupiter-U filter for reflected UV ultraviolet photography

Again more about that new Jupiter-U filter of mine. Also those shots were taken at the wonderfully blossoming Hermannshof Park, Weinheim, Germany. This time it is about a white marshland bog-bean flower Menyanthes trifoliata.

It is UV reflective but quite long wave and does so around 385nm.

Stay tuned, more will follow on that fascinating subject...

[UV] Bidens flower: Baader-U vs Jupiter-U filter for reflected UV ultraviolet photography

Again more about that new Jupiter-U filter of mine. This time it is about a Bidens ferulifolia flower.

All triptychs are presented VIS left, Baader-U middle, Jupiter-U right:



The separating greenish ring between the UV bright tip and the UV dark petal part captured my attention and needs further research.

Bidens is one of my "standard" UV photography targets, as it has a very prominent bright UV petal tip reflection:



It peaks quite prominently around 365nm which my spectral reflection measurement clearly has proven.


Stay tuned, more will follow on that fascinating subject...
