PHOTOGRAPHY; CINEMATOGRAPHY; ANALOGOUS TECHNIQUES USING WAVES OTHER THAN OPTICAL WAVES; ELECTROGRAPHY; HOLOGRAPHY

Description

Class G03 covers image formation and recording technologies using optical waves, non-optical waves (such as X-rays or electron beams), and electrostatic processes. This includes traditional photographic materials and processes, cinematography equipment and techniques, electrographic systems (xerography and related technologies), and holographic recording and reconstruction methods. The class encompasses both the physical media (films, plates, papers) and apparatus used to capture, process, and reproduce images across these diverse technologies.

IPC and CPC are identically structured here. All 6 subcodes exist in both systems.

5 shared codes have differing titles between IPC and CPC.
