Rotifer

#1 Post by dale carter » Sat Sep 26, 2020 3:28 pm

Using my Canon 200D and a mid range custom built microscope, I took a video of this rotifer. It is so difficult to get decent videos of micro organisms, getting the color and contrast right. Will I have to invest in finding a second-hand top of the range Olympus to get the results? probably :shock:

Thank you! I am going to work on seeing if I can improve my videos further, I enjoy the challenge. The background color for bright field was an effort to get it white and not yellowish but that seems to work now.

Thank you! It is so incredible what you can find in your pond. Hopefully I can put more effort into my photographs to produce photographs that people can enjoy. Even though it sounds really strange I try not to harm these creatures, so I put them back in the water once done.

Very nice videos.

The colours (in brightfield) other than the background seem to be spot on, you may be trying to make the background just a little too white,

though I agree a yellow tinge can be annoying.

I looked up your previous post on your microscope and you seem to be using a 7W, 4000k LED.

Have you considered the use of a blue filter, they come in various shades, it might help.

Great video’s. Looks like you have nailed it with the set up you are using. And yes, I too return my samples back to the aquarium.

Thank you for the advice. I am waiting on an order now from Amazon of a 32mm blue filter from Amscope that has left Amsterdam on its way to Cape Town, as soon as I get it that should deal with the problem.
