Undelete did (obviously) not find the file as it had not been deleted... but most of its content should still be there (unless maybe the header... but even then, who am I to know). It should even be located quite straigtforwardly as this disk is mostly used for external backup purposes (not many delete operations)

PhotoRec allowed me to recover the file from the camera SD card, thanks. It didn't find it on my HDD nevertheless, fyi.
