Troubleshooting CR2 to PBM Conversion

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