Real RAS output
Encoded by magick, the same library the command-line tools use — not a renamed extension.
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 RAS
Sun Raster
The native raster format of Sun workstations running SunOS, stored uncompressed or with run-length encoding. Convert from RAS to open images saved on old Sun systems.
