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 MOBI format
MOBI — Mobipocket eBook
MOBI is the ebook format developed by Mobipocket, which Amazon acquired to form the basis of Kindle formats. While largely superseded by Amazon's KFX and AZW3 formats on modern Kindles, MOBI files remain widely distributed and are supported by older Kindle devices.
Common uses
- Kindle-compatible ebook distribution
- Reading ebooks on older Amazon Kindle devices
- Converting ebooks for Kindle compatibility
- Self-publishing ebook workflows
