Very nice images - thanks for sharing.

Some copepods are common in freshwater ponds, typically those belonging to the Cyclopoida. Calanoida copepods are characterized by long antenna and are less common in my experience, though I catch more of them using a plankton net. When I try to mount the Calanoid copepods they almost always rest on...

I have been collecting rotifers for almost 50 years and posted an article with images and a movie of rotifers collected in the summer of 2020. The article includes some new information about rotifers and a list of references. In particular I show two colonial rotifers. Rotifers are just the right si...

I have always wanted to know what the best camera was for taking pictures with a microscope and how good cell phones were - so my son and I tested 4 Dedicated microscope cameras: 3 MP Amscope, 5MP Zeiss Axiocam, 5.5 MP Moticam ProS5 Lite and the Rising Cam 20 MP one inch sensor. I compared them to t...

Hi David - a very simple technique to hold rotifers in place is to put little dabs of vaseline or vacuum grease on the microscope slide to support the coverslip. I use a syringe to apply very small drops of vacuum grease, then place the coverslip on top and draw water out from under the coverslip us...

Thanks for the information that you air dry the solutions on microscope slides. I have tried melting, air drying from different solutions, and evaporation methods with some success. Can you share some the identity of some of the chemicals you are using. I have tested a wide variety of chemicals and ...

Interesting subjects, wish I had an ocean nearby. The darkfield microscopy really compliments the subjects.

HI Karl it would be nice if you shared some information about the chemicals you used, are you melting the crystals or making the slides from solutions and allowing them to air dry?

Rotifers are one of my favourite subjects for photomicrography. The turtle rotifer Testudinella patina is particularly interesting and I have been finding lots of them this year. I photograph them using DIC, Darkfield, Bright field, and polarizing microscopy. Below I have attached a few rotifer imag...

I have been collecting at local ponds and even though I am searching more for rotifers, ciliates, hydra etc I manage to collect a few insect larvae as well. The photos below were taken using a Zeiss Axioscope low power objectives 2.5X, 5X and 10X objectives and often I need to make panoramas to get ...

Very nice darkfield images. Sometimes home made solutions are the best.

Beautiful detail on the Diatom and all in focus.
Very nice

Nice images of ostracods. I see a lot of them but often leave them. You have don a really nice job of photographing them.

Very beautiful photomicrographs. It would be nice to know what the chemicals were. Also did you make these crystals by melting, or drying solutions on a slide.

Cheers
Rob

Beautiful images thanks for sharing.
