    (without saying what file format or filename extension is accepted).

    Thanks - I'll have a look.

    Either of these usual suspects?

    Thanks. I've tried dcraw - won't open the files. rawtherapee is more promising, loads the files and saves them. Just need to get to grips with
    the GUI now.

    Yeah, it looks like all the ImageMagick commands are moving to be
    subcommands of a common ?magick? command.

    There's magick* from ImageMagick (https://imagemagick.org/). I don't
    know whether it'll work on the Sony .ARWs, but I just tested it on a
    handy Nikon .NEF, and it worked just fine.

    worked just fine.

    Hi.

    TIA.

    I don't know about Sony .ARWs, but Nikon .NEFs and Cannon .CR2s both
    contain embeded jpegs.

    A jpeg is everything between 0xffd8ffdb and 0xffd9, so you just need to
    find those start and end positions and dump all of that out to a new file.

    Nikon has small, medium and full res jpegs, Cannon has a tiny and full
    res. I'd expect Sony has something similar.

    Not necessarily what you want to use, though. To get maximum benefit
    from the raw format, you need to do your own conversion from the
    original data.

    Per their website, 7.1.2-11

    https://imagemagick.org/script/download.php

    I use Remi's repo for the package, and that's what I have installed.
    FWIW, it installs these binaries:

    /usr/bin/animate
    /usr/bin/compare
    /usr/bin/composite
    /usr/bin/conjure
    /usr/bin/convert
    /usr/bin/display

    /usr/bin/magick
    /usr/bin/magick-script
    /usr/bin/mogrify
    /usr/bin/montage
    /usr/bin/stream
