ABSTRACT:
A method of picture recording in which a surface of a photosensitive material is exposed to light containing a picture image and the exposed surface of the photosensitive material is superposed on an image receiving surface of an image receiving material so as to transfer the picture image obtained on the exposed surface of the photosensitive material onto the image receiving surface of the image receiving material. Judgment is then made as to whether the surface of the image receiving material to be superposed on the photosensitive material is the image receiving surface by using a detection device for detecting an absorption or reflection factor for light of a wavelength peculiar to the image receiving surface before the photosensitive material is superposed on the image receiving material, so that feeding of the image receiving material may be stopped when the judgment proves that the detected surface is not the image receiving surface.
