PGM Raw in het kort
PGM Raw
The raw PGM branch reflects the practical evolution of Netpbm-style tool formats: keep the tiny header and easy parsing, but move the pixel raster into a binary form that is much more usable for real data sizes.
NEF in het kort
NEF
NEF spans the long Nikon digital-camera era, from early DSLRs through modern mirrorless bodies, which is why its compatibility history matters so much in archive and editing workflows.
