JPM w skrocie
JPM
JPEG 2000 arrived as a major standards effort to improve on classic JPEG, but its practical adoption concentrated in specialist domains rather than in the universal browser-and-camera role held by JPEG.
DNG w skrocie
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.
