Surprisingly easy to do, all you need is a UV source, suitable subjects & a dark room:

wow these look great! This looks like a lot of fun, will have to dig out the old UV light from the loft
Thanks, I was inspired by petrochemist's post to resurrect that image. I have a long-tube blacklight in the closet dating back to 1968. :-)
But note, this shot was done with a shortwave light; standard UV lights work with some minerals, but not as many. Shortwave costs more and needs careful use.
That first one looks good, I've not managed to get flowers to work with my UVIF efforts. The other two aren't visible to me :(
Thanks. Something went wrong, there is only the one picture. I've done a few shots with Nemo UV flashlights that have the blocking filter built in. They are brighter than the Adaptalux, but harder to aim and the light doesn't seem as even.
I was surprised that all the Orchids have different patterns. I was expecting them to all be similar, like Dandelions in UV.
What are you having trouble with?
Thanks,

What are you having trouble with?
I've only had a very limited try, at a workshop I run.
It might be the UV sources I had were not energetic enough (~395nm mainly) or background light levels might have been too high. For most of the other subjects I'd selected fluorescence was strong enough to be clearly visible.
A spooky Halloween image. Pentaz 645Z, Pentax 645 120mm macro, Tiffen Haze/UV 2E, 2 Adaptalux Pod Mini with UV arms. ISO 400 at F8 and 237 seconds. The UV arms have 365nm leds with filtration, probably ZWB-1.
A very long exposure that would probably never work outside. I will try raising the ISO on future shots.
Thanks for viewing,

The results obtained by this lighting technique are interesting. 👍
