Philodina citrina (Video)

[75RR]

This is the same rotifer that I was trying to ID. Now pretty much confirmed to be Philodina citrina.
Kept it overnight in a Slide Mailer. Took this video today.

Good work, very nice and precise video.

I agree with Rodney. And a nice big egg inside.

Good video. What editing software do you use?

[75RR]

Many thanks.

What editing software do you use?

I use iMovie. I have Adobe Premiere (it came with CS4) but it is much too complicated.
I like the simplicity of iMovie. On my good days we are at the same level!

Amazing video! Was that done by DIC?

[75RR]

Thanks.

Was that done by DIC?

Varying amounts of Oblique achieved by offsetting the Brightfield ring of my Phase Condenser.

[zzffnn]

Excellent! You used oblique light very well.

And your photos on this subject (in your other thread) were done the same way as well? Have you tried the universal gradient filter?

And your photos on this subject (in your other thread) were done the same way as well?

Yes. If one offsets the Brightfield ring in a Phase Condenser far enough, one can get a Darkfield effect with low power objectives.

Have you tried the universal gradient filter?

I have a few homemade UGFs (as they all are) which I also use, I tend to alternate the way I achieve oblique.
The effect it gives depends on how the UGF turned out, practice and a little luck.
As in all these effects several things have to all come together at the same time.

Interesting. Is this the same creature we were trying to identify earlier? This one has a definite Corona where the other photos it was not readily apparent. Was it just a matter of watching until they were extended?

[einman]

Ahhh.. yes I saw the Corona extended. Excellent video...

[75RR]

Thanks einman.
Yes they were retracted - see last post in link: viewtopic.php?f=6&t=1364

Excellent! Hang on I have a drawing of this I made in the 80s...(runs to photobucket)...

[75RR]

Thanks Cyclops,
A Rotifer was one of the first things I saw through a microscope (with my Zeiss Junior), was instantly hooked!
