What is FITS?

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

What is MEF?

Mamiya Raw Format (MEF) is the raw image format from Mamiya/Leaf medium-format digital cameras, preserving full sensor data.

When Should You Use FITS vs MEF?

Use FITS When...

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

Use MEF When...

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

FITS vs MEF: Key Differences

  • •FITS uses lossless compression while MEF uses lossless compression — both take the same approach to file size management.
  • •Since both FITS and MEF use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •Transparency: N/A
  • •Storage footprint: Varies from 1MB to several GB for FITS vs 40-80MB per medium-format image for MEF.
  • •Use case fit: FITS targets astronomy, scientific imaging, research and MEF targets medium-format photography, commercial studio — your choice depends on which workflow stage you are serving.

Advantages of FITS

  • ✓FITS applies lossless compression specifically calibrated for Astronomy, scientific imaging, research.
  • ✓FITS enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓FITS guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find FITS support built into virtually every tool that handles Astronomy, scientific imaging, research — no plugins or converters needed.

Advantages of MEF

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

Troubleshooting FITS to MEF Conversion

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