PNM Raw w skrocie
PNM Raw
PNM survived because engineers kept needing a no-drama raster family for scripts, fixtures, codecs, and image-processing experiments where the format should not be the hard part.
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.
