Inspired by Bernd Becher, towards the end of his studies he portrayed former miners from the disused Zollern II/IV mine in text and images.

Rosswog systematically took photographs in many countries, including Ireland, Great Britain, Russia, Finland, Romania, and Hungary.

These photographs document traditional forms of housing that give an impression of pre-industrial life and living in the countryside, as well as their current development facing social changes.

[2][3][4] In addition to these works, which have been reproduced in several publications, Rosswog also takes photographs of the exterior views and the surroundings of the interior spaces that he documents.

For example, in 2003 and 2004 he photographed the changes taking place in the village of Vurpar (Burgberg) in Transylvania, Romania, as a result of the departure of the Transylvanian Saxons.
