Thank you!

The diatom was made with the 25X objective and the larva was done with the 16X.

I think I am slowly beginning to get o.k. results with the digital camera. I tried a projective as eye piece. I had to make a very long tube but I think it gives better results. This rotifer is from a marsh. It think it is Asplanchnopus muliticeps. I had never seen it before. If you keep looking in ...

Thee are some recent images of plankton organisms. A chain of diatoms, Thalassiosira, and a mollusc larva.

Wim

Nice, nice, nice! Great to see you are doing marine. Did you also try plankton?

I have not tried much with the 100X. I do know that you don't always need the matching prisms. I use teh 16X prism for the 40X and the 40X prism for the 25X:)

Wim

Nice to hear you can all see the effect. Yes, just a slight shift is enough but I had to close the condensor doiaphragm a lot so it does not create oblique. It is against the rules but for 3D you need a lot of depth of field. Since I only recently accuired a flash in the past year I became a bit of ...

Very nice results! I hope you'll be able to do more marine stuff. The red algae on your images is Polysiphonia. The spherical diatom is new to me. The square one is Rhabdonema. It can form chains.

Wim

This is a 3D image of a living starfish larva. From the archive, I made it years ago. Instead of the polar filter trick I shifted the diaphragm of the condensor which was a phase condensor. It worked best with the diaphragm closed quite narrow. The first one is for parallel viewing, the second for c...

Work's well Rene! When I have abit more time I'll post some of the images I made in the past with this technique.

Wim

I have been wrestling with Vorticella:) With DIC you can get nice results but because the organism is so three dimensional you can't get all the details in focus. And they move a bit too fast for a Stack. These images show the undulating membrane that directs the food particles inside the cell. Wim ...

Nice image! One trick to get the colour neutral in photoshop is to choose 'adjust levels' and use the eye dropper tool (pipette:), click the midgrey square and click the eyedropper tool on the background of the image that you want to be neutral. (You can set the colour picker to an everage of 5 by 5...

Very nice series, Gerd!
I have once seen this happening and I thought the nucleï were dividing as well (see first image). But that is not the case. They are like that all the time.

Wim

I know I have been posting these too often but just one more because it fits the time of year!

happy holidays!

Wim

Thanks! The dark spots are its eyes. This image was made with a Kodak full frame digital camera. I could borrow it to see if it would be a good solution for digital photomicrography. But it is not as good as I hoped it would be. It gave a magenta to green colour shift over the image and I have not b...

Vrolijk pasen alvast, Rene! Rik, It would be interesting to try to make a 3D version with stacking software but I have not seen it in software for the Mac. I have asked teh Helicon Focus people and they are planning to include such a function but it will take a while before it will be in a Mac versi...

Ken, I think they are fused, like in Stentor.
