DNG in sintesi
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.
PNG in sintesi
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.
