So this is about onions in UV light. These have very cute ball-shaped flowers and I wondered how these would look like in UV "light". The petals seem to have quite some strong UV reflectance to attract pollinators.
So have a look, left is the visual image, middle the reflected UV image and right the image with UV remapped into the visual as blue [click on image gets you a larger image]:
And this one in a bit higher resolution:
So I hope you like these as much as I do....
Stay tuned, more will follow on that fascinating subject...
