Troubleshooting X3F to NEF Conversion

  • !NEF shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted NEF image looks washed out → the source X3F likely uses a wider color space than NEF supports
  • !NEF file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted NEF looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
