Sunflower Pollen

Sunflower pollen in circular oblique lighting.

With the setup I’ve used for the diatoms -posted on another page of this site- I wanted to try sunflower pollen (embedded in Euparal) as well.
This attempt shows a bit more 3 dimensional and natural looking result compared with e.g.darkfield illumination.
Objective is 100x Leitz Fluotar with iris diaphragm.
