What is MOS?

Mamiya MOS (Leaf MOS) is a raw sensor data format from Mamiya/Leaf digital camera backs, used in professional studio photography.

What is CR3?

CR3 files are built around lossless compression. Designed for modern canon dslr/mirrorless photography, professional raw editing, they use the image/x-canon-cr3 MIME type and typically range from varies by content.

When Should You Use MOS vs CR3?

Use MOS When...

Reach for MOS when your priority is mamiya camera raw processing — its uncompromising quality ensures every detail is preserved.

Use CR3 When...

Reach for CR3 when your priority is modern canon dslr/mirrorless photography, professional raw editing — its uncompromising quality ensures every detail is preserved.

MOS vs CR3: Key Differences

  • •MOS and CR3 diverge on compression: lossless compression for the source, lossless compression for the target.
  • •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Alpha channel support: CR3 handles transparency.
  • •Storage footprint: 30-70MB per image for MOS vs varies for CR3.
  • •Primary audience: MOS is built for mamiya camera raw processing scenarios, while CR3 focuses on modern canon dslr/mirrorless photography, professional raw editing — pick the format that matches your output requirement.

Advantages of MOS

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

Advantages of CR3

  • ✓The lossless nature of CR3 means file sizes stay reasonable while handling Modern Canon DSLR/mirrorless photography, professional raw editing efficiently.
  • ✓From mobile devices to enterprise servers, CR3 is recognized and supported everywhere.
  • ✓The trade-off for CR3's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓CR3 is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Best Practices for MOS to CR3 Conversion

  • →Before converting MOS to CR3, decide whether you need maximum quality or smallest file size — this determines which format truly fits
  • →Save a master copy in a lossless format before converting to CR3 — you cannot recover detail lost during lossy compression
  • →Check the color profile: MOS images may use a wider gamut than CR3 supports, causing a visible shift after conversion
  • →Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
  • →Run a single test conversion first to verify quality meets your standards
  • →Strip unnecessary metadata to reduce file size after conversion

Troubleshooting MOS to CR3 Conversion

  • !Converting MOS to CR3 gives blurry output → increase the quality setting before conversion
  • !Colors look different in CR3 than MOS → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → CR3 uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in MOS turned white in CR3 → CR3 may not support transparency
