ExifTool newbie here...
I am planning on adding EXIF date/time information using
exiftool "-alldates<filemodifydate"
I'm wondering what the best way is to preserve the original file modification date? Or perhaps preserve all the original metadata tags for future reference?
Similarly, is there a recommended method for indicating that the EXIF data was manually entered/calculated, rather than applied by the camera when the image was shot? Essentially, I want to make sure that I can figure out which photos had the metadata applied/edited after the fact.
Thanks.

Take a look at the
-P (preserve) option (https://exiftool.org/exiftool_pod.html#P--preserve).

Not within the file itself. You can take a look at the Metadata Sidecar Files (https://www.exiftool.org/metafiles.html) page for some external options. Specifically the "EXIF Files" section for EXIF data or the "MIE Files" for all metadata. Also exiftool will automatically create a backup of any file unless the
Overwrite_Original option (https://exiftool.org/exiftool_pod.html#overwrite_original) is used.

None that I've heard of. It's pretty much something you would keep track of it yourself somehow.
