ORF at a glance

ORF

ORF belongs to the long Olympus digital-camera story, especially in the Four Thirds and Micro Four Thirds eras where portability and serious editing often coexisted.

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.
