Troubleshooting NEF to CGM Conversion

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