this morning is the third day, the flower is almost closed, as soon as a new one opens I'll try like @Andy Perrin with the nemo torch

Thank you Antonio, great interesting photos,
Thanks for the ZB2, I have very surprising and random results, I like the ZWB3.
Let's wait for the rest.

it is a flower of the same plant... there are no striking colors.
it is interesting to see that there are big differences between - anti UV <390nm - yellow - orange - red

Sony A7 f.s. Meritar 50mm f2,9 @f5,6   (2" to 20")

 

all photos were exposed with Nemo 365 nm light
the floor is of pink marble, so it is clear with UV light.
the last photo is ~ VIS

Wow,

That 25A looks excellent.  Might just be my favorite one of the set.

[Andy Perrin]

I am really liking the 25A filter lately for IR. Thanks for the nice set Photoni.

I had forgotten the light green filter ... and a white reference (I used a scissors with satin aluminum handles)
.
I did two different white balances, for the two red and green photos

An excellent addition to the botanical section.

As others have mentioned, it is so interesting to see the views made with so many different filters.
