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.

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.
