Or should I say watercolors? Group portraits are always nice for photography. These are exports from lightroom. I think the sharpening can be better but this is easiest.

Most of these images are from a temporary rain water pond in a farmland in front of my house. This farmland was once the Berkelse Meer, the lake where Van Leeuwenhoek found the first microbes.

How do you obtain the concentration of microorganisms?

I love the 3th one, the darkfield. Nice tones.
The green (with scales?) organism look a bit like "spruitjes"

Fred, they are not Brussels sprouts but Berkels Pandorinas. Pandorina morum is a colonial chlorophyte.

Jacek, the algae are attracted by the light of the microscope. But I pre collected them in a petridish where they concentrated at the area facing the window light. The bottom image is of Coleps and they were attracted by their prey. They are scavengers.

All very nice (special the 3. and the last). In the 1. there is a lot of Codosiga.

Spectacular art!

Jacek raised a good question: how do you get a monoculture of microorganisms at such a high concentration?? Do you treat your stocks of protists like a palette, mixing them in certain proportions to achieve desired effect? Whatever it is you do, the results are breathtaking!

Van Leeuwenhoek would be proud! Beautiful work!

Thank you all, but I don't use any special collecting methods apart from using the pipette as delicate as possible. When I have the sample in front of the window the organisms concentrate towards the light and you can see the swarms with the naked eye. So you don;t even need a stereomicroscope to scoop up a concentrated swarm of organisms. They are not monocultures but sometimes one organism is dominant.

All the shots are really beautiful. The last reminds me that coleps are sort of the piranas of the protist world.

Wim,
Love the Coleps, a very difficiult species to shoot with any detail.
