What if the subjectisn’t a flower? Skin cancer?

It’s just a normal “black light” like at a dance party, or mini golf course, or like the little flashlights they use to check money and ID cards.

Depends on the wavelength. Could be skin cancer, vitamin D, nothing, or your manicure is done

Was wondering why this sounded familiar, saw the article was from 7 years ago (2018) and now I understand, lol.

I need to get a UV filter for my camera…
Psythik@lemmy.world 10 months ago
I need to get UV cone surgery for my eyes. I want to be able to see these colors naturally, not have them fluoresce into a spectrum of colors I already can see.

You don’t need a filter. You need a source of UV light. Plants shine in visible spectrum after being treated with UV. It doesn’t last long tho.

I got a full spectrum converted nex6 in April so I’ve been looking around at filters

Isn’t the sun a source of UV light?

Ultraviolet induced visible fluorescence photography
Sounds complicated, but it’s just shining UV light on an object in a dark room and taking a normal photo with long exposure. If you want to be pure about only picturing visible light, you might need a UV filter, since many cameras can already see a bit of UV despite inbuilt filters.

Is this also how some animals see them?
StellarExtract@lemmy.zip 10 months ago
Technically no, this photographer is putting flowers under a blacklight and photographing them, resulting in a picture of basically what a human would see IRL in that scenario (aside from things like contrast/exposure variances, etc). It’s not really the same as what UV sensing animals would see. These photos are of regions of the flower converting UV light into human-visible visible light (via fluorescence, same thing as a blacklight poster). UV sensing animals are seeing actual ultraviolet being reflected by the flower as well as visible light, so it’s not the same thing.

That’s great! Any guesses what the bottom bars are about on either side of the ‘heart thing’?

That is just remarkable. Augmented glasses that can process this spectrum IRL when? So cool the things just beneath it all

just get yourself a UV flashlight, or bring some flowers to your nearest laser tag arena. this is just how stuff looks under blacklight sometimes (which isn’t to say it isn’t cool, just that you don’t need fancy tech to see it),

Flowers? Banal. Boring. Do hotdog!
