This monday I went to belgium and when I drove back I took the opportunity to go past the Zeeland Deltaworks http://www.deltawerken.com/Deltaworks/23.html to catch some plankton from the sea. It was stormy weather and raining hard. I was completely wet but I caught some nice diatoms. I had only 1 day to photograph them because my camera had to go to the repairs as soon as possible.
This is a Guinardia species. They are diatoms that form helical colonies. It is a stack becaue they are big and deep. Microscopic subjects appear quite flat when stacked so I made the more distant parts a bit darker.

Now I understand, Ken! I also wondered how this diatom appeared in the image while I hade no sample under the microscope. I should have adjusted the illumination a bit better.
However, isn't this the perfect Kohler illumination with the filament projected in the image? Oh no, that was critical (Nelson) illumination.
I am confused!

, i was thinking it looked like that too.
but you can tell it apart cause it looks cut into cells, very interesting shape it has
