my name is Stephan Sprinz. In 2017/18 I volunteered at the NLWKN on the german north sea island Spiekeroog, where I took many of my early uploads. Since then, I've been hooked on (bird-) photography, over the years I also started focusing more on macro photography and astro photography.
Besides nature photography I'm also interested in climate (-activism), cycling and physics and from time to time I upload files regarding those topics.
At the moment I'm doing my masters degree in 'Climate, Earth, Water and Sustainability' at the University Potsdam.
