PFM Raw in het kort
PFM Raw
PFM persists from the era when HDR imaging, rendering research, and tone-mapping workflows needed straightforward file carriers for floating-point image data long before mainstream consumer HDR delivery formats matured.
BPG in het kort
BPG
BPG arrived in the mid-2010s when image engineers were looking for better post-JPEG compression before AVIF and JPEG XL had ecosystem momentum.
