What is 3FR?

Hasselblad 3FR is a medium-format camera raw format used by Hasselblad digital cameras, preserving complete sensor data for professional post-processing.

What is X3F?

Sigma Raw (X3F) contains raw sensor data from Sigma cameras using the unique Foveon X3 sensor technology.

When Should You Use 3FR vs X3F?

Use 3FR When...

Reach for 3FR when your priority is medium-format photography, professional studio — its uncompromising quality ensures every detail is preserved.

Use X3F When...

Reach for X3F when your priority is sigma/foveon camera raw processing — its uncompromising quality ensures every detail is preserved.

3FR vs X3F: Key Differences

  • •3FR uses lossless compression while X3F uses lossless compression — both take the same approach to file size management.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •How transparency is handled: X3F supports transparency, so alpha information is preserved during conversion.
  • •File sizes: 3FR files typically range 40-80MB per image from medium-format sensors and X3F files 25-60MB per photo.
  • •3FR is optimized for medium-format photography, professional studio while X3F is designed for sigma/foveon camera raw processing — choose based on your specific workflow needs

Advantages of 3FR

  • ✓At its core, 3FR relies on lossless encoding — a design choice that makes it perfect for Medium-format photography, professional studio.
  • ✓You won't run into compatibility issues with 3FR — it's a universal standard across platforms.
  • ✓File size management with 3FR: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Medium-format photography, professional studio space supports 3FR natively.

Advantages of X3F

  • ✓The lossless nature of X3F means file sizes stay reasonable while handling Sigma/Foveon camera raw processing efficiently.
  • ✓From mobile devices to enterprise servers, X3F is recognized and supported everywhere.
  • ✓The trade-off for X3F's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓X3F is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting 3FR to X3F Conversion

  • !X3F shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted X3F image looks washed out → the source 3FR likely uses a wider color space than X3F supports
  • !X3F file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted X3F looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
