I would LOVE to use this technique in the creation of panoramics, which I
often make. For the time being, I would have to do an HDR fusion on every
one of the twelve shots I use for a full 360 panoramic. It would be
wonderful to make three or four panoramics of differents exposures and then
export the flattened image, apply exif data to the resulting file and do an
HDR fusion between the three (or four) flattened images and conclude my
panoramic using the final HDR "fused" flattened image.


This being explained, do you have an idea how one could "apply" the Camera
Settings Exif metadata to a selected file ? I would basically want to select
one of the files used to make the flattened image and apply it to the
result.

I don't think that you'll get that to work.

Merge to HDR is smart enough to refuse to merge multiple exposures of the same scene with minor bracketing differences - I know, because I've tried it. So, even if you shoot one RAW file and process it out with massive exposure differences it will still reject the original files as having too little exposure range.

You'd have to make 3-4 separate exposures of each of the 12 shots with huge shutter speed bracketing, merge each section to HDR and then find software that could stitch the 32-bit files together. It'd be easier to get a good light meter, lock the camera off and get the exposure right first time :-)

But, if you are determined to cheat the EXIF data you should open an image with the correct EXIF and then paste a different image over the original and re-save the file!
