Troubleshooting ARW to RAW Conversion

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