Something to be aware of about "RAW" images: most dSLR will encode a full-size JPEG _within the raw image_ (that you can pull out with `exiftool`) which frequently is what the resulting JPEG would be (which, on some cameras, includes image enhancements through "computational imagery")--so there really isn't a disadvantage to shooting raw (versus raw+jpg). (I found this only after shooting jpg+raw for years, and then digging into a bunch of different camera outputs to support them via PhotoStructure).

> most dSLR will encode a full-size JPEG _within the raw image_ in what quality though? Because the advantage of using RAW+JPEG is that you can set 90%+ quality settings for JPEG in the camera.

  I think it's less. If I've got my files right locally, my Canon SL3, on RAW+JPEG, the JPEG is 7.4MiB and the JPEG embedded in the CR3 file (the "raw" file from Canons) is 2.3MiB. So, less. Between them, you can tell if you zoom in far enough (on the smaller one, there is clear artifacting) but it's they're both 24 MP photos so you have to get pretty close to the pixels to tell that. (I've only just gotten a decoder working on CR3 to the extent where I can extract those, though. One thing that hasn't changed since the OP is that camera manufacturers are still determined to making parsing their custom formats impossible by documenting absolutely nothing. Good hardware, terrible software.)

    LibRaw is great, BTW.

  > in what quality though? JPEG basic with Nikon. I'd assume it's the same for the other manufacturers, although that's guesswork. The newer cameras (Nikon Z for example) don't just include a single JPEG either, but multiple smaller versions for e.g. rear LCD display, which can also be of higher quality.
