Ola Kolehmainen (born 1964, Helsinki) studied photography at the University of Art and Design in Helsinki. His photographs almost exclusively depict sections of building facades. They are organized according to strict principles of order, showing rows of repetitive basic patterns or symmetrical constructs. The austerity of these images is occasionally broken by elements that circumvent this formalism: trees or houses mirrored in the facades. The works are produced using the Diasec process, which means that the environment is reflected in the surface of the photos as well as in the images themselves – a calculated component of his work.
