Abstract

Photographs of M 33 in blue and infrared light have been used to prepare a two-color photograph by the dye-transfer process. This photograph shows the hot stars of Population I as blue or white, while the red supergiants of Population I and the red giants of Population II appear red. Features of the two-color photograph and advantages of the two-color method over black and white composite photography, and advantages of the dye-transfer method itself are discussed.
