Abstract: Outlined are some of the problems of the users of direct-positive subtractive color films, such as Ansco Color and Kodachrome, in producing acceptable duplicate images which in some cases may be third-generation reproductions. An experimental project will be described in which it was found that it is possible to produce duplicate images which may be directly compared with the camera originals by exposing the duplicating film with filters transmitting three relatively narrow spectral bands. While no attempt has been made in this paper to deal in any detail with the theoretical aspects of color reproduction, a number of factors which are of great concern to the users of color materials have been noted — particularly the establishment of visual acceptance limits for color images, and the influence of processing upon the shape and relationship of the three-color density curves representing an image of a neutral wedge.
