I took a few ARW pictures with a Sony A6000 (a.k.a. Sony ILCE-6000). I would like to convert them to PNG or TIFF with ImageMagick. I tried:

convert DSC00288.ARW test.tiff


convert DSC00288.ARW test.png

but the output image is not good (colors are faded):

Am I misusing ImageMagick or does the latter simply fail to properly support ARW conversion?

With -verbose:

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.

  • Thanks. ImageMagick-6.9.0-Q16 on Windows 7 SP1 x64 Ultimate seems to use dcraw instead. I tried to replace the dcraw by the binary version on the official website, as the a6000 (= ILCE-6000) is said to be supported, but ImageMagick didn't like it :/ I'll try again tomorrow, but if any idea is welcome! I also opened the .ARW file directly in ufraw (latest version) but colors are also distorted. – Franck Dernoncourt Jan 2 '15 at 4:37

    Since ImageMagic just converts the raw file to PAM as a preliminary step and the consumes that file. So why not just call dcraw directly (specify TIFF output) yourself? Then you can figure out the conversion options more directly. – JDługosz Jan 2 '15 at 9:16
