The second picture taken with Scanning Electron Microscope I wanted to show here.
A friend of mine discovered a new species of Utricularia ("Wasserschlauch"), a carnivore plant.
His diploma thesis is about this discovery and along with his study, he asked me to make a electron-microscopical picture of these Utricularia-Seeds.

I did and he's happy with them. But I did also other things, such as a 3D-picture (which I won't show here because you'll ned red/blue-goggles to see the effect). And I did this picture, which will be a birthday present for him.

Since all electron-microscopical pictures are greyscale (well, electrons have only *1* wavelength.... to show colours that's a bit too small bandwidth *GG*), I had to do a little trick:

Our microscope has to electron-detectors, one that detects the direct return-beam, and one that detects secundary dispersing electrons. So I've got two different pictures with two different greyscale-shadings of the very same object. Merging them, using RGB-Channels, created this very beautiful effect (together with the mandatory cleaning and optimizing ^^).

Please consider, that these colours do not reflect reality! They are created digitally just to show three-dimensional structure a bit better and to make it more pleasing in an artistic way
