Abstract
A data recording system is disclosed in which level of intensity of light emitted by a light source to illuminate selected items of data on a data carrier to permit projection of the image of the data onto film material simultaneously with exposure of the film material to image-wise light from an external scene is automatically made higher or lower as camera shutter speed is increased or decreased. The total amount of light emitted by the light source and allowed to reach the film material is maintained generally constant and recording of data is effected efficiently at all shutter speeds.
