In the late 1970s Richard Holden decided to try colour photography, after eighteen years of working in black and white. However, he was uncertain as to which colour process to choose. He wanted colour prints of archival standards, a problem at the time because Ektacolor prints were unstable and colour shifted over time. He also wanted a print that exhibited the same sharpness and resolution as black and white. He finally settled on the Cibachrome print, also called the azo dye print. Cibachromes glow with saturated colour and maintain high detail. In the works seen here, the artist has exploited the colour and formal qualities of his subject matter. The city appears in hyper-intensity, and the print seems as if lit from behind.
