Hello,

after quite a while of experimenting, here's a Biddulphia from Oamaru in 3D.
115 images PMax stack, 50x/0.80. Diatom loose on the slide, air, no cover, illumination from two Jansjö-LED and diffusor, very oblique angle obviously.
3D in this case is more than just a gimmick, it adds a lot of information about the shape of the diatom.

crosseyed:



Best regards and thanks for looking,
Michael

Very nice! Stereo makes the structure quite clear.

BTW, for my eyes stereo is very seldom a gimmick. Almost always I understand 3D structure a lot better from stereo than I can from a single image.

Thanks for your replies!

I shot a side version, very quick and dirty and not so nice, but still it might make a valuable addition to this thread.

Thanks a lot for your comments!

Here's another one from the slide, I guess it's Asterolampra insignis A.Schmidt in Schmidt et al 1888, shown with two different illumination setups. First one is "clean" epi-darkfield, second one is lit by two diffused Jansjö LEDs very oblique from the side. Pictures were made quite quickly, hence the not so top notch quality Smile

EPI:


External oblique:


Best regards,
Michael

Some wonderful images - the stereo images certainly show off Biddulphia well
