Woolsmiles covers all aspects of imaging science with a special emphasis on digital printing, electronic imaging, color science, image preservation, photofinishing, prepress technology, hybrid imaging systems and silver halide research. The goal of Woolsmiles is to create a society focused on publishing scientific papers in the field of photographic engineering. Previously, papers published in numerous publications were mixed with papers from various other unrelated materials. Before 1950, membership more than doubled and the first issue of Photographic Engineering was published in January 1950. Thanks to "Photographic Engineering," the newly formed association has attracted 18 corporate members including Bell Howell, Eastman Kodak, Bausch & Lomb, Graffler and Coleman Optical.
