Keld Helmer-Petersen was a danish photographer, who grew up in Copenhagen. He was gifted a Leica camera in 1938 which started up his career in the world of photography. Keld was good at spotting trends within photography at the time and how it was all war influenced which then progressed into The New Objectivity. Albert Renger-Patzsch was a big inspiration for him and opened him up to abstract photography and in 1948 he published the bilingual book 122 Farvefotografier/122 Colour Photographs. Colour photography was his first style but he began to experiment with contrast in black and white photographer, which is what he is now known for. He was influenced by constructionist artists and their interest with industry’s machines and architecture’s constructions. His photos displayed large amounts of structure and patterns within industrial areas.
