HDR at a glance

HDR

HDR raster formats became important in rendering and lighting workflows before consumer-facing HDR delivery stories matured in mainstream media formats.

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.

FAQs

Why convert HDR 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 HDR to PFM Raw?

This conversion changes how the format behaves in downstream tools and delivery environments.

What should I review after converting HDR to PFM Raw?

Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
