Cone count is my guess. Of the photoreceptors in the eye - Rods see in low-light and cones see in color. Some animals lack or have different cones compared to humans. Hence why bees can see “bee purple”
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.
Is this also how some animals see them?
Yee. I saved this image for a Caption this.
“Bird Vision activate!”
Walks straight into glass door
That’s great! Any guesses what the bottom bars are about on either side of the ‘heart thing’?
Saddam Hussein in UV light.
It’s very unclear/nonsensical
I spent like twenty minutes looking. I’m stumped!

It seems to be a commonly used image stolen from Klaus Schmidt https://photographyoftheinvisibleworld.blogspot.com/search/label/bird vision but strangely none seem to have the lower bit. How odd…
