:) 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!
