PTX in het kort
PTX
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.
X3F in het kort
X3F
Sigma raw support is closely tied to the company's Foveon sensor story, giving X3F a reputation and workflow profile that differ from more mainstream Bayer-centric raw ecosystems.
