Troubleshooting DNG to CR2 Conversion

  • !CR2 shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted CR2 image looks washed out → the source DNG likely uses a wider color space than CR2 supports
  • !CR2 file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted CR2 looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
