Troubleshooting XPM 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 XPM 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
