PURPOSE:To form a stable image of high contrast and high density later on a recorded photographic material by subjecting the area having developed silver to high illuminance exposure. CONSTITUTION:Chart paper 2 of constant density is superposed on the information adding area of an original 1 to be recorded, the original 1 is photographed using a photosensitive material 3 forming developed silver such as a monochromatic negative film or an X-ray film, and developing treatment 4 is carried out to obtain a recorded image 5 having developed silver present in the area corresponding to the part covered with the paper 2 at 0.1-1.63mm.phi average diffusion photographic density. The area of the recorded image 5 corresponding to the paper 2 is exposed by irradiating high intensity energy beams through a positive film by 10<2>-10<3>J/cm<2> quantity of energy for <=10<-2>sec to print additional image information 6 on the recorded image 5. |
