I like the 3D perspective!

Very nice? Would you mind telling how that was done? I do have one diatom that is mounted similar to your picture but of course nowhere near the quality of your posting.

You should make a stereo pair if possible.

Hello and thanks for your answers.

The picture was made with a Nikon MM60 Measurescope, a little bit taylored for my purpose. Placed on the floor for safety, the thing is a beast at roughly 80 kg that would most likely break my table.



Sorry for the stage and other mess, the whole scope is still a building site.

The diatom is lying loosely on a slide, that is tilted with a ball head specimen stage.



Of course this is a 10x Mitty, not the 50x. one single Jansjö through a paper diffusor, that's it.

I'll try to make a stereo, but it takes considerably more time to do than a single view, so I have to try to find some time for it.

Best regards,
Michael

Very nice setup, what is that black "thing" with the stepper motor on the focus ? Gearbox ?

[sushidelic]

The MM60 has a triaxial focus. The stepper sits inside a 3D printed enclosure, that connects to the "middle" focus (the coarse focus is achieved by rotating the big lever). The shaft of the stepper is connected to the fine focus. Very minimal but works perfectly.

Like I said beautiful image and thanks for taking the time to post the additional images of the actual setup you used.

Ooh, never seen an MM60, it looks very good.

Is the motor "fixed" on a coarse(r) focus while turning a fine(r) focus knob?

I find it odd that such a distorted-looking organism has such a round outline.

Looking at your main image -- which is very nice! -- I'm suspecting that you spent quite a bit of time in tuning parameters and/or manual retouching.

The image is great, but as you say, doing a similar version in stereo could take a lot longer.

On the other hand, one way to save a lot of time with stereo is to just skip retouching altogether -- just run PMax and accept that there will be a lot of artifacts. Often artifacts from PMax, even if easily visible, will not interfere with understanding the 3-D shape. Then the combination of the single clean image and the stereo-with-artifacts image gives, well, certainly not the best of both worlds, but enough good to be very helpful.

Good job, Super photo !

Thanks for your replies!

Exactly

just run PMax and accept that there will be a lot of artifacts. Often artifacts from PMax, even if easily visible, will not interfere with understanding the 3-D shape.

True, and considering that I will need to scale the stereo down to match de forum's rules, I think a straight PMax with little retouching will work fine. I already processed a stereo pair inside Zerene, and it looked quite convincing. I hope I'll finish it today.

@James: I had a glimpse at your Measurescope before you edited the post, really a nice beast! No need to delete the image, at least I didn't mind .

Best regards,
Michael

Quick stereo:

[Smokedaddy]

Sweet, thanks for making the stereo.

Ridicuously fabulous.
