Berliner artist Florian Balze (http://www.florianbalze.de) designed the S-Bahn access in HH Altona Diebsteich
It is a ceramic digital print behind glass. An overlay of two images: the underlying one consists of a gesture painting that he photographed from a very low and out of center point of view to give it a landscape association. He used an analogue large format camera shifting from a sharp foreground to an out of focus background in the upper area. The overlaying rectangular structure is made with spray paint.
