ABSTRACT:
Apparatus for printing a selected region of a photographic negative onto a photosensitive paper to form an enlarged and cropped photographic print includes means for projecting the photographic negative onto first and second zoom lenses, each of the zoom lenses having an adjustable magnification. Means are provided for defining, by adjusting the magnification of the first zoom lens, the selected region of the photographic negative to be printed. Means are provided for adjusting, as a function of the magnification of the first zoom lens, the magnification of the second zoom lens so as to image the selected region of the photographic negative onto the photosensitive paper. Further, means are provided for exposing the selected region of the photographic negative through the second zoom lens onto the photosensitive paper for a predetermined period of time.
