Subfolder by date

[neebah]

I would like to run a command to move photos to a new folder structure as follows. 

Year\Month\Day\

based on whichever date I prefer (taken, digitized, etc).  I would also like any photos that aren't dated accordingly which tag I use to go into an unspecificed folder.  Any way to do this.

exiftool -d "%Y/%m/%d" "-directory=/path/to/UnspecifiedFolder" "-directory<DateTimeOriginal" FileOrDir

If the DateTimeOriginal exists, then it overrides the first directory instruction.
