CR2 in het kort
CR2
CR2 became the dominant Canon raw family through the long DSLR era, so huge real-world photo archives still depend on stable CR2 decoding and migration paths.
DNG in het kort
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.
