ORF in het kort
ORF
ORF belongs to the long Olympus digital-camera story, especially in the Four Thirds and Micro Four Thirds eras where portability and serious editing often coexisted.
MEF in het kort
MEF
Digital photography fragmented into many manufacturer-specific raw formats because camera makers optimized for their own sensors, metadata, and software ecosystems rather than for one shared public raw standard.
