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 FAX format
FAX — Group 3/4 Fax Image
FAX is a generic extension used for raw CCITT Group 3 or Group 4 fax image data files. These files contain compressed monochrome page scans as transmitted by fax machines, and are typically converted to TIFF or PDF for archival and viewing.
Common uses
- Fax document archiving and recovery
- Converting raw fax streams to viewable formats
- Legal and business fax record keeping
- Processing fax server received files
