I believe he is referring to JPEG-HDR, not (unused, rarely implemented) 12 bit
JPEG.
See Greg's publications on the matter for more details.

Well, if we can use those for testing, I would be definitely interested.

You mean the 12bpp option in "traditional" JPEG? Well, sure, but not in
this test - that's done already - I'm currently looking into floating
point support, and for that into images that really need more range than
12bpp could address.
I do have the IJG code, which supports 12bpp lossy as a compile-time
option (unfortunately, somewhat buggy, but fixable); I suppose this is
what you mean?
Thanks,
Thomas
