Very impressive pictures!
By the way: A.radiosa is not longer a species name. Many different amoebas take that structure when disturbed or free swimming.

It is not that I don'want, but it could become a long lecture about polarization...

No post processing, apart from a bit of more contrast sometimes. I needed some years to get the results today...
Your are now on the right way - keep on experimenting, also with all kinds of plastic foils for retarders!

Hi,
Nice and rather rare found! Campylodiscus sp. is correct. Typical is its movement, according to its saddle-like shape: juggling periodically without locomotion.

Great pictures!
If you could take the Daphia in polarized light, all the now white crystals would come in colors!

A "foil retarder" is a small piece of clear colorless plastic foil, placed between polarizer and condensor. It shifts the pol-colors to a higher order to make them more interesting. Check different material.

Hi Barry,
please try it with a foil retarder, to make the different elements better to distinguish.
