The colours are quite different because of the different backgrounds.
Not only because of the background but also because of the angle of incident light.

I absolutely fell in love with the beautiful demoiselles when I first saw them with thei typical metallic cobalt blue/cyan.
It was quite difficult to get them in this color style so when you see my pictures they allways have a touch of green as well.
Here is one where the color at the wings is almost perfect but missing sharpness on the body and ISO3200 is killing the details.20180609_0052.JPG

The colour of the wing from my reading is not due to pigmentation but the structure of components of the wings, microcrystals, photonic crystals etc and so the colour varies according to the angle of viewing and whether the light is reflected or transmitted.

Nice shots Alan!
Same for Maximilian, but I have to agree with the Alan's explanation of the variable color!

I still have no new photos of this sort, will try do get some in the weekend.

+1 and 100% with you
If I ever wrote something sounding different, I wasn't precise enough.
It is because of the micro pigmentation/crystals in combination with angle of viewing AND angle of incident light.

You are absolutely right. It's really interesting how the banded demoiselles look intensely blue when they flutter and the light reflects from their bands but their wings have black bands when viewed against the light and you just see the transmitted rays, like this one. And in the flying shots you can sometimes see a pair of black and a pair of blue wings.

Hi Alan.
Sorry, it wasn’t meant as a dig at you, I could probably have worded it better but I’m no English professor! :)
My intention was for those posting here who didn’t know of it’s existence to be aware of its presence and be able to look at some other great work.

Cheers, Graham.

Well, I could say that it doesn't include damselflies or that it had become dormant. But, the truth is I had missed it! Anyway, we are having good fun with the new thread and its revived interest in this fascinating area of nature.
