ABSTRACT:
A photographic exposure apparatus has a light path for directing an optical pattern of a display image from an image display to a photosensitive material and a light path for directing an optical pattern of a negative image from a negative film of the photosensitive material. The two light paths are selectively switched from one to the other to project each of the display and negative images onto the photosensitive material at a common exposure station. A mirror is disposed turnably to be movable across and between the two light paths. A mirror drive turns the mirror through a predetermined angle to switch between the light path for projecting the display image and the light path for projecting the negative image.
