DCM at a glance

DCM

DICOM grew out of the need to exchange imaging data across scanners, archives, and clinical systems without throwing away the surrounding context that makes a medical image usable in practice.

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.
