A method of printing digital data onto a photograph using infra-red ink and using an ink jet printing process. The data stores details of an image taken by a camera, which has been transformed by a proprietary image processing program, loaded separately into the camera. The printed data also includes a copy of the program. The data is printed in a fault tolerant form enabling the copying or recovery of the transformed photograph or of the original thereof notwithstanding damage thereto.
