His personal interest lies in contemporary artists and their creative world.

The instant photographs produced by the Polaroid reveal Mark's familiarity and closeness to the subjects he portrays.

In the series Natura Morta (2017), he photographed confiscated objects from the evidence room of the Federal Agency for Nature Conservation.

These items, mostly falling under species protection regulations, were originally intended as souvenirs before being seized by customs authorities.

Mark presents these objects in a way that emphasizes their allure, only to evoke stronger repulsion from the viewer.
