Hi.

Can anyone suggest software I can use on Pi5 to convert a number of .ARW
(Sony RAW files) to JPEG?

TIA.

Either of these usual suspects?

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.

* it used to be "convert", but when I used convert, I was told
'WARNING: The convert command is deprecated in IMv7, use "magick"
instead of "convert" or "magick convert"'. For the record, "convert"
worked just fine.

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

I've no experience of Sony .ARW files, but ufraw handles my Canon .RAW
files well enough, and claims to support a number of Sony cameras
(without saying what file format or filename extension is accepted).

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.

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.

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

Of course, if you're on debian then you only have the magick and convert commands. (the package is woefully outdated as usual)

I have all the magick commands available on Debian -- always have.

OK, turns out I was still reading from the bookworm packages instead of
trixie. Still stands that most packages on debian are pretty outdated
though, since I think trixie was released a few months ago.
