:) I also like to feed them in photogrammetry software, which prefers to
have as much unprocessed info as possible.

Generally yes, not with Foveon. (regularly used a Sigma DP1x long ago)

All cameras that I’ve shot raw with embed a preview image into the raw
file. It can be extracted for example with:
dcraw -e <raw_file>
The question is how to make Emacs aware of this. Ideally, viewing raw
images also works with [picpocket][1], a nice Emacs image viewer that I
only discovered today.
Anyhow, very nice summary of raw images!
