if you have problems with the videos, you must install the "divx-video-codec". You can download the codec from this site:

I use this codec because it reaches a high compression rate combined with a good qualtiy.

With the aid of the filter "logo" you can overlay any bitmap. I use a CANON Powershot A85 camera both for recording the videos and the fotos. No special s...

Hydra in a video

Hello, the characteristic behaviour of a hydra (cnidaria) can be demonstrated best in a video. I found this species sitting on a root of a common duckweed. The section of the root with the hydra was cut off and observed on a concave slide in a few drops of water. No coverslip, darkfield, lens 4x/0.1...

strange kind of a ciliat

Hello, I am new to this forum and I want to introduce myself with a picture of an unknown, strange kind of ciliat that I recently found in a small pond in a forest near Wuppertal, Germany: http://home.arcor.de/dr.ralf.wagner/Bilder/ciliatdgenerated-englforum.jpg It shows zoochlorellae and e.g. in co...
