Copepod, Amoeba and Algae

Here are some images from old photo sessions this summer/fall. The last one (Arcella) was a real pain and is hand-stacked. It was impossible to get Zerene or Helicon to do a decent job, so I hand stacked it from 14 images and manually selected the focus areas using the Zerene retouching module. Took...

Re: Unknown Organism Found From Tongue Sample

Looks like a piece of fiber. It can move due to movement in the fluid as it dries out. Does not look like anything (alive) I have seen. 8-)

Re: Olympus CX21. Your opinion?

I think 500 is a decent price. I had a CX40 which looks very similar. They also have infinity objectives and I paid $700. That was like 5 years ago. I would for sure go for infinity objectives as it is more future proof. It will allow you to upgrade to a more advance stand later if needed. Microscop...

A fellow forum member suggests the the Uroglena in fact is a close relative, Uroglenopsis. There are actually entire research papers on the topic on how to identify the differences between the two species (!). Looking through the paper, I think Uroglenopsis is the correct ID.

The camera I have now is quite good at freezing motion due to its high shutter speed and firing rate. What camera and your technique please. I switched from Canon 6D to Sony A9. The 6D was useless for water and oil immersion due to shutter vibration. Even though I could carefully select the shutter...
