Why do Sony A6000 ARW files look faded when converted with ImageMagick?

I'm converting Sony A6000 (.ARW) RAW files to TIFF or PNG with ImageMagick, but the results look faded compared to the original. For example:
convert DSC00288.ARW test.tiff
convert DSC00288.ARW test.png
Does ImageMagick properly support Sony ARW files, or is there an issue with how RAW conversion is being handled? I also checked with -verbose to see what helper tool ImageMagick uses.

ImageMagick (by default) uses ufraw-batch to convert RAW files, including ARW. I'd make sure you have the latest version of ufraw installed. The Sony ILCE-6000 (aka α6000) is on the supported list, so it should be okay. If you add the -verbose flag to convert, it should show you exactly how it's calling out. My guess is that if you update the ufraw it's using, the problem will be solved.

ImageMagick itself does not fully decode most RAW camera files directly. By default it typically calls an external RAW converter such as ufraw-batch for ARW files. If the converted image looks faded, the likely issue is the RAW conversion step rather than PNG/TIFF output.
For Sony A6000 / ILCE-6000 files, support should be available, so first make sure the installed ufraw/ufraw-batch version is up to date. Using ImageMagick with -verbose is the right way to confirm exactly which helper program it is invoking.
In short: you’re probably not misusing ImageMagick; the weak result is likely due to the external RAW decoder/version it is using. Updating that RAW conversion tool should help.
