About PFM

Overview

PFM (Portable Float Map) is a minimal image format designed to store floating-point data, specifically for High Dynamic Range (HDR) imaging. Unlike standard formats that clamp values between 0 and 255, PFM stores raw 32-bit floating point numbers, allowing for values far brighter than white (pixel values > 1.0) or negative values (useful for data maps).

Technical Details

The format is an unofficial extension of the Netpbm family (PPM/PGM). It starts with a simple header: `PF` (for RGB) or `Pf` (for grayscale), followed by dimensions and a scale factor (which also indicates endianness). The data follows as raw binary 32-bit floats. Its simplicity makes it the 'CSV' of HDR image formats—easy to write a parser for in a few lines of C++.

History

Popularized by Paul Debevec and the computer graphics research community in the late 90s as a way to exchange HDR light probe data before widely supported standards like OpenEXR existed.

Common Use Cases

  • HDR Light Probes: Storing captured environmental lighting for 3D rendering.
  • Depth Maps: Storing Z-depth passes from 3D renders.
