About the SUN format
SUN — Sun Microsystems Rasterfile
SUN (also known as RAS) is the native raster image format of Sun Microsystems' SunOS and Solaris operating systems. It was the standard format for screenshots, icons, and general graphics on Sun workstations from the 1980s through the 2000s.
Common uses
- Legacy Sun Microsystems/Solaris graphics
- Converting old Unix workstation images
- Historical software documentation screenshots
- Archival recovery of Solaris-era media
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
