Graduated as a film director from the Danish Film School in 1973, though continued with photography when it became evident that his future was not to be in film.

A photographer since his early youth, Krass published his first book, Skygger af Øjeblikke (Shadows of Moments) in 1978. His photographic work emerges from two traditions: The Scandinavian melancholy on the one hand and the 'flaneur' tradition from the Parisian school on the other. 

Starting out in black and white, Krass has persisted in developing and modernizing his artistic expression so that his production today also includes work in colour. His work originates from a fertile and imaginative thought process, a stream of consciousness that is clearly evident in his later books.

This book was published in conjunction with the exhibition Krass Clement. Indstillinger. at the Vendsyssel Kunstmuseum in 2009."
