DNG at a glance
DNG
DNG emerged when professional photo workflows were already fragmented across many undocumented vendor raw formats. Adobe positioned it as a common archival and interchange option rather than just another camera-native format.
KDC at a glance
KDC
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.
