ARW vs 3FR: Key Differences

  • •ARW and 3FR 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.
  • •How transparency is handled: 3FR supports transparency, so alpha information is preserved during conversion.
  • •ARW files are typically 20-40MB per photo while 3FR files range 40-80MB per image from medium-format sensors
  • •ARW is optimized for sony camera post-processing, professional editing while 3FR is designed for medium-format photography, professional studio — choose based on your specific workflow needs

Best Practices for ARW to 3FR Conversion

  • →Before converting ARW to 3FR, 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 3FR — you cannot recover detail lost during lossy compression
  • →Check the color profile: ARW images may use a wider gamut than 3FR 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 ARW to 3FR Conversion

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