PFM Raw at a glance
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.
MOS at a glance
MOS
Digital photography fragmented into many manufacturer-specific raw formats because camera makers optimized for their own sensors, metadata, and software ecosystems rather than for one shared public raw standard.

FAQs
Why convert PFM Raw to MOS?
Convert to MOS when maintaining compatibility with Leaf-originated capture files or preserving source material from medium-format studio workflows.
It is primarily an archival and editing format.
What changes when converting PFM Raw to MOS?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to MOS adds camera raw data. Moving to MOS removes HDR content.
What should I review after converting PFM Raw to MOS?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
