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 FITS?

Flexible Image Transport System (FITS) is a scientific data format used primarily in astronomy for storing and transmitting images and datasets.

When Should You Use 3FR vs FITS?

Use 3FR When...

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

Use FITS When...

Reach for FITS when your priority is astronomy, scientific imaging, research — its uncompromising quality ensures every detail is preserved.

3FR vs FITS: Key Differences

  • •The core technical difference: 3FR relies on lossless compression whereas FITS 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.
  • •How transparency is handled: FITS supports transparency, so alpha information is preserved during conversion.
  • •File sizes: 3FR files typically range 40-80MB per image from medium-format sensors and FITS files Varies from 1MB to several GB.
  • •3FR is optimized for medium-format photography, professional studio while FITS is designed for astronomy, scientific imaging, research — choose based on your specific workflow needs

Advantages of 3FR

  • ✓3FR applies lossless compression specifically calibrated for Medium-format photography, professional studio.
  • ✓3FR enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓3FR guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find 3FR support built into virtually every tool that handles Medium-format photography, professional studio — no plugins or converters needed.

Advantages of FITS

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

Troubleshooting 3FR to FITS Conversion

  • !Converting 3FR to FITS gives blurry output → increase the quality setting before conversion
  • !Colors look different in FITS than 3FR → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → FITS uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in 3FR turned white in FITS → FITS may not support transparency
