Yes and I refer all to Soul Dr. post.

Larry refers to "Incredible captures of flowers using ultraviolet light!" yes beautiful... it is seeing the world as the Bee sees, our visible palette is pleased. My years of experience... maturity.. OK, getting old I recall the psychedelic days of Perter Max posters. Give a quick read:

With simple equipment, we can make our own UV flowers visually bloom. The purple bulbs are not much, but the purple compact fluorescent do emit strong UV. I have a 100-bulb UV flashlight that costs about $23 on Amazon. "KOBRA Black Light Flashlight 100 LED Lamp Blacklight 18W 385-395nm" Shine it at night and the small flowers in the grass visually talk.

I am a bit confused. Is she using just a regular unmodified digital camera with no filters with just UV light sources? Or is she doing it the way I know of / have read of using a modified camera with the UV/IR/AA filter removed from the sensor and a Visible Light Blocking filter installed? Or is she strictly doing UV Fluorescence Photography? That is a different technique again. There are at least three general sorts of UV light (sources) UV A, UV B, and UV C. The short wave C type can be damaging to skin and eyes! I once played with some UV Fluorescence of Vinyl LP records. Some of them are Fluorescent and look psychedelic. Most are just black under the lights I used. I have a IR Modified Camera for Infrared Photography use. That takes me into the world of invisible light as well. But it is very different and more limited than UV techniques. But I am not sure what Ms. Lombardi is doing.

Yes this is UV induced fluorescence, which is much easier to do than photographing UV (which typically gives fairly monochrome images). Even with a full spectrum converted camera, that is sensitive to UV, you need a filter that blocks visual & NIR yet passes UV (The more affordable filters leak NIR which the camera will be much more sensitive towards - they might be OK if using film but then metering is complete guesswork without feedback) and you need a lens that transmits UV most don't to any significant degree, those made for UV imaging are like hens teeth. I've tried both and at best managed a proof of concept UV shot, where some UV features could just about be visualised. The UVIR was dead easy, with everyone in the workshop session I lead getting results, however my subjects were much less attractive:

Don Komarechka has also made interesting ultraviolet photos.
