Carl Georg Shillings was fond of hunting and in the period from 1896 to 1903 made many trips to German East Africa (German colony in Africa that existed in the territory of modern Tanzania, Burundi and Rwanda). There, he hunted animals that were subsequently made stuffed, adding to the collection of many German natural-science museums.
However, most of the time Shillings paid photos. He was one of the first photographers who started shooting animals in their natural habitat. He is also the pioneer of night photography. In 1905 he published the first book dedicated to the “hunt” in German East Africa
