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 RLA format
RLA — Alias/Wavefront RLA Image
RLA is a multi-channel image format developed by Alias Research (later Alias|Wavefront, now Autodesk) for 3D rendering and compositing. It stores standard color channels alongside auxiliary channels such as depth (Z), object ID, and normal vectors, enabling sophisticated compositing workflows.
Common uses
- 3D rendering compositing with depth and ID channels
- VFX multi-pass rendering output
- Converting legacy Alias/Maya render output
- 3D studio animation frame storage
