摘要

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