What is RAF?

Fujifilm Raw Format (RAF) contains raw sensor data from Fujifilm X-Series and GFX cameras with unique X-Trans sensor processing.

What is SGI?

Silicon Graphics Image (SGI) is a raster image format developed for SGI workstations, supporting high-quality rendering and scientific visualization.

When Should You Use RAF vs SGI?

Use RAF When...

Reach for RAF when your priority is fujifilm photography, film simulation processing — its uncompromising quality ensures every detail is preserved.

Use SGI When...

Reach for SGI when your priority is legacy sgi workstations, 3d rendering — its uncompromising quality ensures every detail is preserved.

RAF vs SGI: Key Differences

  • •The core technical difference: RAF relies on lossless compression whereas SGI uses lossless compression.
  • •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •Transparency: Supports alpha channel
  • •File sizes: RAF files typically range 20-50MB per photo and SGI files Moderate to large raster files.
  • •RAF is optimized for fujifilm photography, film simulation processing while SGI is designed for legacy sgi workstations, 3d rendering — choose based on your specific workflow needs

Advantages of RAF

  • ✓The lossless nature of RAF means file sizes stay reasonable while handling Fujifilm photography, film simulation processing efficiently.
  • ✓From mobile devices to enterprise servers, RAF is recognized and supported everywhere.
  • ✓The trade-off for RAF's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓RAF is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of SGI

  • ✓SGI compresses data using lossless methods, keeping file sizes manageable for Legacy SGI workstations, 3D rendering.
  • ✓Industry-wide support means SGI files open anywhere — from legacy systems to the latest devices.
  • ✓Lossless quality makes SGI the gold standard for archival and master copies.
  • ✓From professional software to open-source alternatives, SGI works out of the box.

Troubleshooting RAF to SGI Conversion

  • !SGI shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted SGI image looks washed out → the source RAF likely uses a wider color space than SGI supports
  • !SGI file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted SGI looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
