CR2 w skrocie
CR2
CR2 became the dominant Canon raw family through the long DSLR era, so huge real-world photo archives still depend on stable CR2 decoding and migration paths.
PFM Raw w skrocie
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.

Często zadawane pytania
Why convert CR2 to PFM Raw?
Convert to PFM raw when HDR rendering, tone-mapping, or scientific-imaging workflows need floating-point pixel values to survive intact between tools.
It is especially useful as an intermediate format for graphics research, physically based rendering, and analytical image-processing pipelines that operate on scene-referred data.
What changes when converting CR2 to PFM Raw?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to PFM Raw removes vector scaling. Moving to PFM Raw removes camera raw data. Moving to PFM Raw adds HDR content.
What should I review after converting CR2 to PFM Raw?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
