Agfacolor is a color film process developed by the German company Agfa in the 1930s. It was one of the first successful color negative films, allowing photographers to capture vibrant colors in their images. The process became popular for both amateur and professional photography, especially after World War II. The Agfacolor system used a complex layering of color-sensitive emulsions to produce realistic color reproduction. It was widely used in various formats, including 35mm and 120 film, and contributed significantly to the growth of color photography in the mid-20th century.
