ABSTRACT:
A platform-shaped device is designed to be placed over the illuminating aperture of a color-controllable light-box of known construction, and under a camera which is loaded with a roll of color film of slide-forming size and character, and which is focused on the central area of the platform. The device has at opposite sides a reel for holding, guidedly feeding and receiving a roll of developed black-and-white negatives previously made from the usually much larger black-and-white art work. The device also has means (e.g. a geneva-movement mechanism) for accurately sequentially positioning in the camera field, each one of a series of frames to be converted to color-slide frames in the camera. A pair of laterally movable thin blackened masking plates are manually movable in guides to expose different laterally constricted areas of the negative for each color to be projected therethrough from the light-box. Another pair of thin blackened masking plates are also provided for horizontal fore-aft movement to expose areas constricted at right angles to those exposed by the laterally movable plates.
