DNG vs RAF: Key Differences

  • •The core technical difference: DNG relies on lossless compression whereas RAF 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.
  • •Alpha channel support: RAF lacks transparency support.
  • •Storage footprint: 15-40MB per photo for DNG vs 20-50MB per photo for RAF.
  • •Primary audience: DNG is built for raw archival, cross-platform photography workflow scenarios, while RAF focuses on fujifilm photography, film simulation processing — pick the format that matches your output requirement.

Troubleshooting DNG to RAF Conversion

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