JPEG 2000 has an option for 12 bit resolution which might be 
important to purists who are into "perfect" rendition of  "real film".

DICOM, the open format for medical graphics is also available though 
it is intrinsically monochrome - like an X-ray. Color information can 
be included by making linked red, blue, and green files. The medical 
folks are slowly moving toward JPEG 2000. I should hope that they 
also care about images at least a lifetime old.

And while I'm at it, RAW formats are uncompressed representations of 
pixel values. Specifying the format is little more than providing the 
bit-length of a pixel, (8, 12, 24, 32,. . .) and the number of pixels 
that are in one complete scan line. A file of that sort would be far 
easier to figure out, next century on Mars, than the discrete 16x16 
two-dimensional cosine transforms of a JPEG.
