PGM Raw at a glance

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.

3FR at a glance

3FR

Hasselblad raw workflows are closely tied to medium-format capture and to the brand's studio and commercial-photography lineage, which gives 3FR a different practical role from mass-market DSLR raw families.
