Camera Makers Defend Proprietary RAW Formats Despite Open Standard Alternative

Camera manufacturers continue to use different proprietary RAW file formats despite the 20-year existence of Adobe's open-source DNG (Digital Negative) format, creating ongoing compatibility challenges for photographers and software developers. Major manufacturers including Sony, Canon, and Panasonic defended their proprietary formats as necessary for maintaining control over image processing. Sony's product team told The Verge their ARW format allows them "to maximize performance based on device characteristics such as the image sensor and image processing engine." Canon similarly claims proprietary formats enable "optimum processing during image development." The Verge argues that this fragmentation forces editing software to specifically support each manufacturer's format and every new camera model -- creating delays for early adopters when new cameras launch. Each new device requires "measuring sensor characteristics such as color and noise," said Adobe's Eric Chan. For what it's worth, smaller manufacturers like Ricoh, Leica, and Sigma have adopted DNG, which streamlines workflow by containing metadata directly within a single file rather than requiring separate XMP sidecar files.
