About the HDR format
HDR — Radiance RGBE High Dynamic Range
HDR (Radiance .hdr) is a high dynamic range image format developed for the Radiance rendering system. It stores luminance information far beyond standard 8-bit images using a shared-exponent encoding, making it the standard for HDR environment maps in 3D rendering.
Common uses
- 3D rendering environment maps (IBL)
- HDR panorama photography storage
- VFX and CGI lighting reference images
- Tone mapping source images
About the PPM format
PPM — Portable Pixmap
PPM is the full-color member of the Netpbm family, storing each pixel as RGB values (8 or 16 bits per channel). It is widely used as an interchange format in image processing scripts, being completely uncompressed and trivial to parse from any language.
Common uses
- Color image processing and scripting workflows
- Intermediate format in image conversion pipelines
- Scientific and research image interchange
- Generating images programmatically
