Today I hold a two hours lecture on "autofluorescence of plants" for member of the German Mikroskopie Forum. The focus was  - what else could it be - on photography and their challanges. The presentation can be found here.

Sac of spores (sporangium) of Dryopteris filix-mas is among the "must-haves" of microscopists. This year I was lucky and found them in the perfect status. The black dots are the spores flung as from a catapult.

The Photoadventure 2020 takes place!! The team of the Photoadventure had been working very hard in the past few weeks and months, organized a new venue (the Pyramide in Voesendorf/Vienna) and made the event "corona-ready". We offer two lectures:

• Warum Makrofotos so oft misslingen (why macrofotos fail so often)
• Bildwirkung in der Fotografie (the message of an image)

Most recent works with focus on micro- and macrophotography are presented in the exhibition section of the event.

You find more under events. Visit the online ticket shop.

Yesterday I had the chance to take a picture of this beautiful insect, a male banded demoiselle (Calopteryx splendens). It was early morning and quite cold at the river Feldaist (Upper Austria). In order to be ready to fly, the dragon fly trembles with its wings.

Several new items made their way to my collection of minerals.

Currently I am faszinated by the roots and rhizome. This is another picture of this series. It shows the root of Garlic mustard (Alliaria petiolata) with a side root.
