MEF w skrocie
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.
PGM w skrocie
PGM
PBM, PGM, PPM, PNM, and later PAM come from the tool-centric tradition of keeping image interchange formats easy to parse, script, and transform.
