In my observations of freshwater samples, I encounter such an individual very often. It's undoubtedly Rotifer. I think I became a little friends with them, hence the title of the film. Nothing extraordinary - rotifer is rotifer. But this particular individual allowed us to look inside and showed us ...

Hi Don.
You got some nice color shots at the beginning of the video.
The more you delved into the structure of the leaf, the more subsequent shots lost their color.
But I guess it's natural.
I liked.

Hello A nematode filmed in a bright field lands inconspicuously. It is gray and not very noticeable. This one got new clothes and looks different now. It reminds me more of a moving gold piece of jewelry. PZO DIC, 20x. I'm trying to get a gray background color, but no luck so far Regards Maciej HPoY...

Great video
Various lighting techniques.
The main actors are quite famous.
The music is excellent.
I watched it in the morning and this music set my whole day in a positive sense of the word.
I watched your clip with great pleasure.

Hello. Another sample of fresh water from the forest pond. And once again there was a beautiful, green CLOSTERIUM on the glass. It's probably quite a large individual, because its internal structure is clearly visible. I particularly enjoyed recognizing elements such as the nucleus and pyrenoids. Of...

Hello. In today's sample taken from the container, I found a whole cluster of diatoms. It looked like some kind of diatomaceous garbage dump. Initially, my attention was drawn to a rather long chain. Based on the literature, I came to the conclusion that it is Tabellaria, but I may be wrong. The vid...

This microorganism is probably Nauplius. I saw them a few times, but they moved so fast that they couldn't be filmed. This one is particularly lethargic and I was able to get a better look at him. The lighting technique is DIC PZO. The video is quite long, but please be patient while watching becaus...

Hello KurtM. Thank you very much for your words of encouragement and understanding. I became interested in microscopic observations some time ago, but I keep discovering something new and fascinating. There is a lot of material to watch and it is really difficult to make sense of it all. And this, i...

Hello WWWW. Of course you're right. This is closterium. I don't know what made me decide to use the wrong name. Perhaps the fact that there were a lot of diatoms around that are not visible in the frame. And these diatoms stayed in my subconscious. Well - I'm just a reckless amateur and I don't see ...

Hello Today the subject of my video is a nice, motionless diatom that posed beautifully in the foreground. A sample from a forest pond taken two days ago. The technique is DIC PZO. Nothing fancy, but I'm happy with my new toy and playing with the colors. For now I'm filming stationary objects, but I...

My first video made using the PZO DIC technique. Presents little Daphnia. I placed the preparation on a basic glass that had a special indentation. This protected the microorganisms from being crushed by the cover glass. 20x lens. Pentax K3 camera. Filming speed 25 frames per second. Regards Maciej ...

Hello After a long break, I decided to refresh this thread. I thought that I owed it to all forum members who gave me advice and tips on how to solve my problem related to PZO DIC. In particular, I would like to thank forum member "apochronaut". Your comments were very useful and even inspiring for ...

Amoeba. Found in a sample taken from a large puddle in the forest. Some amoebas are very lazy. It moved with astonishing speed. I filmed the amoeba at 25fps and I think it's played back at that speed now. I don't remember what lenses I used, but I think they were 25x and 40x. The video is quite long...

Hello bkt. I'm glad you liked my video. You write that you are learning. I do it all the time. I am learning nomenclature, observation, interpretation. And of course I make lots of mistakes. That's how it is. As for the fact that Cyclops is immobile, I think it is due to the strong adhesion of the c...

At the beginning of the video, a single eye is clearly visible. Then, as we move forward, we see a large number of eggs in the back of the body. At high magnification, you can see other passengers located between these eggs. Sweet water. Sample from last year. CZJ Jenaval microscope. Lighting is a s...

Some kind of nematode.
Filmed exactly a year ago, in March 2023.
The video was shot at a strange, for me, speed of 59fps.
Fresh water, of course.
It looks innocent enough here, but actually they are different creatures

Some ciliates again today. Based on illustrations from the Internet, it's probably Euplotes, but I'm not sure. There are plenty of these oranisms and matching them to the correct name is quite a feat. Water collected from the pond in mid-February and kept in a jar at room temperature for several day...

Hello.
Some ciliates today.
Taken today from a jar of fresh water.
The container was left at room temperature for a few days.
Oblique lighting.
Without this lighting he was almost invisible.
25x and 40x lenses.
CZJ Jenaval microscope.

Hello Another old video extracted from the vast archive on my hard drive. It shows a small community of Vorticella ciliates (I think). What is amazing to me is their synchronization and the speed at which their flagella contract. If I remember correctly, I used an oblique light. Lenses: 12.5x and 25...

Marcel.
Yes, you're right about the diagonal lighting effect. To achieve this, I partially cover the beam of light under the condenser with a black plate.

Ddy5 - I forgot to write that this small 10mm disc must be black. I'm sure you know this, but I wanted to supplement my post

Hello everyone. I am very sorry that I did not participate in such a lively discussion about these two videos. I didn't expect this and I must admit that it surprised me (in a very positive sense of the word). Thank you all very much for your time and opinions. English is not my natural language, so...

To be honest, I don't really understand what it means to lower the position of the interference head. My head rests on the port to which I connect the eyepiece and I view the image on the camera screen. Physically, I can't lower the head position any further or I don't understand something when it c...

Hello apochronaut. I'm already answering your question. In this particular case, I did not use EPI lighting. I only wrote that my old Fluoval has two types of lighting: DIA and EPI. So far, I have only used EPI illumination for observations in reflected light (autofluorescence). I used the remaining...

Hello everyone. And thank you all very much for your kind willingness to help me. Karol - thanks for the idea to post the problem on Facebook. It will undoubtedly be more convenient for me to use my native language Scarodaktyl - thank you for the suggestion regarding lenses. My DIC PZO set includes ...

Hello I have been the owner of DIC PZO for a long time But it was only two days ago that I connected it to the microscope. I don't have the original PZO microscope, so I installed it in the CZJ Fluoval body. To do this, I used my various "patents and inventions" Despite initial difficulties, I put i...

Hello. I found this creature in a drop of fresh water. It was late fall last year. From studying the literature, it appears that it is some representative of Closterium. I really like this half-moon shape. As you can see, the sample was quite thick because I couldn't get both ends of this alga sharp...

macnmotion,
PeteM,
Javier.
Thank you for your very nice opinion.
You really gave me great pleasure

The first observation of the crystallization process this year.
There was a mixture of two liquid flower fertilizers on the slide.
I used polarized light with an inherent compensator as lighting.
I filmed without a coverslip.
12.5x lens.

Hello. My very old video from summer 2022. Back then I was still shooting very long shots. This material is almost eight minutes long. Nowadays, I no longer produce such long videos, although I must admit that I really like watching microorganisms for a long time Today something from the Vorticella ...

From time to time, such views appear on my glass.
This is a bit troublesome because you can't focus on a single individual when there are so many of them.
I'm lazy .
I didn't feel like counting them.

Maciej.
