(b Kazanskaya-na-Donu, 1881; d Moscow, 1948). Russian photographer. He studied at the Moscow School of Painting, Sculpture and Architecture from 1901, then worked as a painter, turning to photography in the second decade of the 20th century. He experimented with complex laboratory processes but in his mature period concentrated on conventional printing. His experience as a painter was reflected in his photography, for example Ayvazovsky’s Cliff on the Black Sea (1920), with its enigmatic light and soft transitions. In the 1920s and 1930s Yeryomin worked on several major photographic cycles including Crimea and Central Asia, and his series Old Moscow and Palaces and Estates in the Moscow Area recorded numerous architectural monuments. He exhibited in the USSR and abroad, winning awards for his work. He also illustrated books on the art of photography. In the mid-1930s he tried his hand at photojournalism, but landscape and architecture, photographed with a soft-focus lens, remained his favourite subjects.
