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 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! [1]: https://melpa.org/#/picpocket
