Photographer Timm Suess is passionate about capturing decay in our world. He travels to abandoned factories, clinics, and military installations to photograph the places people leave behind.

In a talk at TEDxGundeldingen, Suess details his Chernobyl Journal: a project that led him to the city of Pripyat, Ukraine, which was abandoned after the Chernobyl disaster.

Above, photos from the project, which documents places lost to the disaster.
