my name is Stephan Sprinz. In 2017/18 I volunteered at the NLWKN on the german north sea island Spiekeroog, where some of my uploaded pictures were taken. Since then, I've been hooked on (bird-) photography, over the years I also started macrophotography and astrophotography.
Besides naturephotography I'm also interested in climate (-activism), cycling and physics and from time to time I upload files regarding those topics.
All my pictures on Commons can be found here, pictures of mine that are used outside of Wikimedia projects can be found via Google.
