Yeah it's a real shame.

The technology has existed for a long time, but 24bit lossy jpeg has just been too successful to be replaced for most uses.

Jpeg LS is popular for medical imaging.

Jpeg 2000 is popular for satellite imaging.

There are non-Adobe plugins for Photoshop if you look for them...

My understanding is that jpg compression achieves smaller filesize by discarding data.  I've never heard of exceptions to that at any level of jpegging.

You can confirm that by examining a file at the pixel level, but why argue?  If you wish to retain all the data the camera collected, just don't jpg.  If you feel you don't need all the data, the issue is moot.

My pro shooter's opinion was that the publisher was going to be receiving a jpgged file from him anyway, and that magazine quality print wouldn't be able to reproduce the minutiae of uncompressed data anyway, so wotthehell.

I'm not sure he does "art" shows of his work, too.  He's been an editorial National Geographic photographer all his life.
