A diatom mounted directly on a sand grain which, in turn, is mounted on the end of a 1mm optical fibre. The *only* light in the scene was transmitted up through the sand grain via the fibre (with a Schott halogen light source shining down the other end).

200 shot DMap stack, 50x Mitty on 135mm tube lens for 33x onto FF running in APS-C crop mode. FoV is <0.4mm wide.

Very nice shot, and I find the lighting very good, and the "idea" well done for that one.

Very dramatic, and as usual you avoid the common micro-photo artefacts, so that there is no clue about the size of the object. That could be a diatom or a big glass bowl on display in a fancy store.

"Now your just showing off!" Which is a good thing, very clever and I assume very tricky to pull off.

Very very nice image!. A pleasure to see you resuming your work with diatoms

I can't imagine how to do it.
Did you place any liquid or solid media for light transmission between fiber-sand grain-diatom?
