>manipulate what is left?
When I am faced with editing a JPEG I bring it into Affinity Photo and change it to 16-bit. While that doesn't bring back what was lost, it does help mitigate quantization errors and staves off posterization a bit as long as you don't make any heavy duty edits.

I see that I can export a jpeg from LR as a 16 bit TIFF or PSD and then open the new file in LR or PS. Would that be roughly comparable?

I only mention Affinity Photo for that is what I use. Opening the JPEG into PS and changing it to 16-bit there would be the same as me opening the JPEG in Affinity Photo (just that I don't use Adobe software any more).
I specifically left out file formats. As noted JPEG is generally 8-bit. But that's a limitation of the editing software not the JPEG specification which allows support for 12-bit.
As already mentioned, you've already lost a good amount of information that you can't get back. If you need to edit, the issue is mitigating the artifacts.

Thanks for that - otherwise I agree, this is damage limitation, not something to aim for!

Having the two card slots I've been saving NEFs and Fine Large jpegs - just out of curiosity, to see if Nikon does better PP then me. Result:- It probably does, but I can't really see it. Ho, Hum!
The main lesson I'm taking away from this is to check the bottom corner of that top screen regularly!
Having said that, I would observe that changing capture file options seems a strange choice to favour with button options. I mean, how often do people need to alter their image quality options - apart from those in the middle of nowhere when the waterhole really kicks off, of course...

I'll take a look, but you are correct - I am really only concerned, right now, with making the best of my bad jobs...

• The best option is to bring it into Lightroom and do whatever you would normally do in post. Obviously you have less data to work with. Color correction or changes, especially a substantial white balance shift, will be exceedingly difficult. But having adjusted thousands of client JPGs over the years. JPG post processing is not the end of the world. And, of course, once in Lightroom the question of other file type is moot.
• Photoshop might be marginally better for a truly lousy JPG. There are some tricks with layers — duplicating what you have and then working with blending modes (and possibly masks) to make adjustments — but to me the hassle of working in Photoshop in this instance just is not worth the result. For the rare time that I do take a JPG into Photoshop, I save it as a Photoshop file. It’s lossless and a reasonably-efficient file size.

Thanks. I really appreciate perspectives like this. I started out, having discovered how easy it can be to change file types by accident, feeling that it would be sensible to explore any options, and now I know - it's a rabbit hole best ignored :grin:

If you go to my post over here;
https://www.nikonians.org/forum/topic/424-2592-2592/how-to-light-a-photograph-to-take-a-photograph-of-it-
You will see that I have a picture taken in jpeg, by my wife, on a very small camera (5meg) around 16 years ago. I was trying to give my wife a surprise and get a reasonable print for Xmas (10 x 8).
My point is that the last image in my post was me using the new Enhancer in PS. It gave a reasonable result from such a tiny file 130kb.
As you say your camera was capable of raw, I am assuming you have about 24meg at your disposal, so your jpegs would be of a far better quality than mine, to start with.
Here is a youTube turotial link;
hope it helps.

However I am planning to try Super Resolution on some of my older smaller jpegs and I guess that a happy outcome will at least partly depend on accepting sizes that work rather than aiming too large. Thanks for the link - I hadn't found this one!

Apart from the possibility of artefacts some LR tools seem to be relatively ineffective with jpegs. No great surprise there, after all, a lot of data has been discarded, but would exporting the file as, say, a TIFF make it easier to manipulate what is left?
