Number of shots taken by Nikon D80 camera

The Nikon D80 camera contains a EXIF tag value that counts the number shots taken

<th>

</td>

<td>
  Makernote
</td>

<td>
  Exif.Nikon3.ShutterCount
</td>

<td>
  Long
</td>

<td>
  Number of shots taken by camera
</td>

This can be extracted by running the following command

exiv2 -pt picturename.JPG
...
Exif.Nikon3.ShutterCount                     Long        1  5263

This example shows that there have been 5263 shots taken.

I guess this EXIF tag exists on Nikon D40x, D60 and D70 also, but this is not verified.
