Keld Helmer-Petersen born the 20 August 1920 was a Danish photographer who got his breakthrough in the photogrpahy world  when he published 122 Farvefotografier/122 Colour Photographs, this was a collection of experiments with shapes inspired by the work of Albert Renger-Patzsch and  Neue Sachlichkeit. In the book was a collection of photos that he thought would only work in colour and not black and white.

Keld Helmer-Petersen was born and grew up in the Østerbro quarter of Copenhagen. He started taking photographs in 1938, when he received a Leica camera as a graduation present.^[1] At an early stage, he became aware of the trends in international photography; in the 1940s he subscribed to the US Camera Annual and in this period became familiar with German inter-war photography, which had developed at the Bauhaus and in the Neue Sachlichkeit (The New Objectivity) movement. In his later life he released a series of other books which focused on a different light to other work in colour, as the books only contained black and white images.
