Oxeye UV.

A humble trial I did back in March to shoot an oxeye flower (gone by now) in visible and UV and then tried to create what they commonly call "bee vision" image. I've included here the two separate shots for comparison; the normal (or visible light image) and the UV one.
Since both were taken handheld, there are some unmatched edges here and there of course. Despite using an IR block filter, the visible light image did have a red tint originally but it was easily fixed in post-process (my bad, because I was supposed to calibrate the WB already before shooting). As for the UV shot here, this is after a quick WB fix in post-process of course (the image was purple/red out of camera).
There are actually numerous ways to combine such images and typically I don't have a fixed workflow for this yet; I just try whatever makes a better visual impact, kinda.

The weather events probably cause the air around leaves to produce weak electrical discharges

If you think about it, you can’t be sure that what you see for the color red, for example, is what anyone else in the world actually sees. All you can be sure of is that we’ve all been …

UV Onion.

I feel you won't be eating onion after getting sick of all these shots lol
Anyway, this is one humble trial to shoot the flower(s) in ultraviolet and combine it with a regular or "visible light" image. A technique that is usually dubbed as "Bee Vision" (but it's not scientifically proved that bees do really see in this manner but it's merely an imaginary approach). In simple terms, two images are shot; a regular one and one with UV-Pass filter, then the blue channel of the regular one is replaced with the UV shot. I've done this with sunflowers and oxeye flowers and the difference were clear between UV and visible light images, but here with the onion it seems not much difference to be seen. It is believed that such patterns that are visible under UV only are used by bees for guidance.
The shot was done outdoor so there is a shake for sure but I tried my best to overlap the two images. Because of using auto ISO, the ISO value between the two shots differs as well. The shot was made with 50mm, and the final image here had been cropped a great deal to focus on the flower only.
