PNG in het kort
PNG
PNG emerged in the mid-1990s as a web-friendly alternative to GIF, and the format later became part of the W3C standards stack.
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.
