Does anyone know if JPEG stores the settings from a digital camera and how to read them?
ie: ISO setting, etc.?

I like to experiment with settings, would be nice not to have to write each one down.

Perhaps you want the exif data

Make sure you have the exif libraries install, and at the prompt, type

# exif blah.jpeg

I was wondering - doesn't GIMP 2.4 support EXIF data now? I had a JPEG with some EXIF data in it that I could read with GQView but I couldn't find a way to read the data in GIMP. Is there one?

AFAIK, there was an exif plugin for the Gimp, but I can't find it now.

There was an exif reading plug-in on the old registry (I forget who wrote it -- Simon Budig?) It was read-only; it couldn't change an image's exif. It doesn't seem to be on the new registry. Is there any way to get to the old registry to grab a copy of older plug-ins? (It's great that the new registry has moved to registry.gimp.org -- it's much better than the old one, but I hope that doesn't mean we've lost all the plug-ins in the old registry's database.)

The exif plug-in as it existed on the old registry didn't work with GIMP 2.4. I updated it a while back and got it working for reading exif, but it looked like it would be a big job to make it read/write and I dropped it. If anyone wants it, I could upload the version I updated later this week (right now I'm away from the machine that has the source). The updates were pretty straightforward.

Yes, there is. The link to the archive is given in the switch announcement: http://registry.gimp.org/node/235

I was wondering why this wasn't merged into the internals so decided to do a Bugzilla search. See
http://bugzilla.gnome.org/show_bug.cgi?id=56443

Looks like it's not as straight forward as one might think for supporting EXIF data across multiple file formats or multiple versions of EXIF-like data. Ideally this is what you want so that the file, of whatever type, when read by its file plugin would store the exif data in parasites (or similar) and a generic exif viewer/editor would alllow access to it. Changes to the data would then be preserved when the image is saved. However a generic solution like this has been under discussion for some time.

In the interim and for the simple case, a file-type specific exif viewer plugin could be written that uses (as the bugzilla entry points out) the newer exiv2 library.

Or just get Akkana's latest version of the old JPEG exif plugin back into the registry. :-)
(See http://registry-archive.fargonauten.de/plugin?id=4153 for the old plugin)

Thanks! The old exif-browser plug-in is available at: http://registry-archive.fargonauten.de/plugin?id=4153

Bill (William Skaggs) is the author, according to the AUTHORS file in the source.

I found I needed to update it to get it to build and run. I've put a diff at
http://shallowsky.com/tmp/exif-browser/exif-browser.diff and a tarball of the updated plug-in at http://shallowsky.com/tmp/exif-browser/exif-browser-updated.tar.gz

Note the /tmp/ in those paths -- this plug-in should really live in the registry, not on my site. But the new registry isn't letting me log in right now (should the login info from fargonauten.de carry over?) In any case I want to wait and see if Bill wants to list it under his own name.
