RAF vs DNG: Key Differences

  • •RAF uses lossless compression while DNG uses lossless compression — both take the same approach to file size management.
  • •Since both RAF and DNG use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •Alpha channel support: DNG lacks transparency support.
  • •RAF files are typically 20-50MB per photo while DNG files range 15-40MB per photo
  • •Primary audience: RAF is built for fujifilm photography, film simulation processing scenarios, while DNG focuses on raw archival, cross-platform photography workflow — pick the format that matches your output requirement.

Troubleshooting RAF to DNG Conversion

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