UV/IR Thermal or Xray Photography Humans happen to use visible light naturally but now we can go beyond the usual wavelengths we appreciate, to find out more about our world and ourselves.

Default Intensity of insect perception beyond color!

I'm so sorry for the butterflies and bees that they do not see as we do. The first image is so beautiful. The others, mimicking the insect;'s view, appear by our standards much more diluted in impact.

But it could be that the insects, which have compound eyes, see much more nuance in detail than we do at the viewing distance as they can build up a far more detailed movie of what is going on. When identifying the texture and nature of a detail, their simple but marvelous neurocircuits must do wonders with the multiple close but distinctly different angles that the moving information provides them. surely this is processed differently that we might expect. So to imagine bee vision, perhaps we need 3D glasses and some ability to look at the image from different angles.

3D acquired from so many angles must give extraordinary depth perception and allow for algorithm to pull out detail we might miss.

So while I might be sorry that the bee cannot appreciate your first Nikon image, Klaus, I am sorry that we do not have real time multiple lenses to get their extraordinary sense of dimension that they take for granted!

Actually, the vision of a bee and butterfly is rather blurry compared to our human standards, especially when further away and better the closer it gets. Hence why some plants have developed flowers with rather bright (UV-) markers for them to get visible and standing out quite boldly against the grass and background - even against flowers without such markers, developing a competition edge ;-)

I'm surprised that all those eye units don't give the little critters some exquisite advantage over us! After all a compound eye seems ideal for looking more critically at structure!
