IR fluorescence trichome of snail shell

[Fandyus]

Technique explained in previous post.

IR reference (720nm longpass)

visible reference

fluorescence under green

fluorescence under blue

fluorescence under 395nm

trichrome

(the "dust" is contamination on my PTFE sheet, which this shell was laid on)

That looks like a visible light photo, although not so similar to the visible reference. It has a sort of “natural” look.

Yes, it's quite odd that the shell is also brown while imaged this way.
