In other words, it is impossible to submit un-PP images. Also, if as most UHHers advise, we shoot RAW, then can't we submit them as they will have to be manipulated?
Very few, if any, publications or photo labs accept raw files.
Why?
A raw file is likened to a frame of exposed, unprocessed color negative film. It may be converted to a bitmap image and "developed" in infinite ways, by many different applications, all of which interpret the data in different ways.
In the case of labs, they don't support raw files because it would be very difficult to collect software that converts every type of raw file from every model of camera. Likewise, it would be ridiculous to assume that a raw file should "look" a certain way. It was bad enough to assume that, or for a lab to attempt that, back in the days of film and optical printing! (I worked in both film and digital photo lab environments, and attended conferences and seminars with others who did the same. We compared notes over lunch, often!)
True experts at photo adjustment and raw file conversion are expensive. They usually can make FAR more money as commercial photographers than as lab technicians.
Yes, some agencies, forensic organizations, and media editors want an "unedited" image. By that, their intention is most often to avoid all traces of fakery. They don't want images with subjects moved, parts of the scene retouched out, parts of the scene artificially added from other images, etc. For that reason, they may request straight-out-of-camera, un-edited, un-adjusted JPEGs. They are willing to give up some measure of image quality in exchange for more probable authenticity.
SOME of these people will accept JPEGs that are converted and developed from raw files outside the camera. But they are likely to insist you provide an unaltered comparison/verification image from the camera, as a check against unauthorized content manipulation.
