Troubleshooting MEF to CRW Conversion

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