I love photography and always illustrate my blog entries with photos. Some photos in the blog are taken by me. More of them can be seen on the page My Portfolio.
Also I share the photos from the sources like the free media repository Wikimedia Commons, including images provided by the German Federal Archive (Deutsches Bundesarchiv). A few examples can be seen below.
In 2010-2011, I posted weekend columns in order to draw attention to some works of art in photography. The sources, from which the images came, were specified. Later these columns were moved to the Tumblr branch of my blog.
