Visual artist and photographer Katja Mater constructs an image by layering multiple moments in time. When making a drawing or object, different exposures are made on the same negative at various points in the process, physically building up an image in a cross-exchange of visual information between the subject, whether painted on paper or constructed object, and the film. This results in abstracted, monochromatic works depicting geometrical and vaguely textured forms. This book features several series of Mater’s works, also explaining in detail the working method behind each image, illuminating the complex processes she employs to achieve a final result.
