Yee. I saved this image for a Caption this.

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.

Hotdog? Banal. Boring. Do a kickflip

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

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 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.

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),
