About HDR

Radiance HDR

The HDR format from the Radiance renderer, storing each pixel as red, green and blue values with a shared exponent byte, so it holds a far wider brightness range than 8-bit images. Most HDRI environment maps ship in this format. Use it to light 3D scenes, or convert from it to get an ordinary 8-bit preview.

About SGI

Silicon Graphics Image

The raster format of Silicon Graphics workstations, also seen with the .rgb and .bw extensions, stored raw or with run-length encoding. Convert from SGI to open images from old IRIX software and 3D pipelines.
