color enhaced visible fluorescence of onion and lemon cross sections

I think I used the Nemo torch, or some other filtered 365nm LED lightsource.

The photos differ quite a lot from what the things looked like in real life. I enhanced the colors to highlight subtle color differences.

Both images are high res so feel free to enlarge them.

Intriguing how the unusual colors give these an abstract but still organic "feel". The lemon makes me think of deep ocean creatures. Very well done!

They look like they could be displayed in an abstract art gallery. The second one especially.

Thanks a lot for the compliment, Stefano.

@Fandyus WOW! They are fabulous. They deserve to be printed large and displayed. 

Thanks for sharing,

Thank you! Coincidentally, one of my friends has recently expressed interest in printing some as presents for her relatives, I was very pleased to hear.

That second one reminds me of one of my high voltage plasma globes.  Superb!

Thanks a lot!

Just saw your lemon on Rob Shea Infrared Photography Live Stream! 

Haha, small world isn't it. Do you also submit your images?

I thought about it.

I did ask whether Rob would do any UV in the future.

It's likely he will, I know he plans doing UV himself but it's hard to say when.

Nice! Btw one printing method I really like for our kinds of photography especially (given the saturated color palettes we often have around here) is the printing-on-glass technique popularized by Fracture.

Have you tried it?

It sounds very interesting and I wonder if such printing is available in Europe too.

Yes! I have used it twice - both given to my mother as gifts so I can’t show you directly. 

 

This was the second of the two:

It came out fairly well.
