Copyright info and Aperture - EXIF or IPTC

With the firmware update 110 for the Nikon D300 one has the option to add a copyright note in the images, just like one could already before with the Nikon D3.

This is excellent news. It would have been even more excellent news if the information had been easy to find outside the world of Nikon.

There are now three fields to play with in the camera. They are all entered under the Setup menu.

1. Image Comment is entered under the menu heading "Image Comment".

2. Artist is entered under the heading "Copyright Information".

3. Copyright is also entered under the heading "Copyright Information".

If you use low end products like gimp (2.6.1), Preview or iPhoto (7.1.5), none of this information is to be seen anywhere.

The following explains how some more high end applications display the fields.

Image Comment
  • Aperture - field not visible.
  • Bridge CS2: "Camera Data (EXIF)". Field called "User Comment".
  • Capture NX: "Camera Settings" > "Shooting Info". Field called "Image Comment"
Artist
  • Aperture: EXIF field called "Artist". It does not seem to be visible unless you go in and customize the Metadata displays.
  • Bridge CS2: "IPTC Core", field called "Creator" AND "Camera Data (EXIF), field called "Artist".
  • Capture NX: "Camera Settings" > "Shooting Info". Field called "Artist"
Copyright
  • Aperture: Field not visible. There is a field in Aperture called "Copyright notice", but it is not filled with the information of the Copyright field in the D300.
  • Bridge CS2: "IPTC Core". Field called "Copyright notice".
  • Capture NX: "Camera Settings" > "Shooting Info". Field called "Copyright". (It is not under IPTC as it is in Bridge.)

In Nikon View NX all the three fields appear with the same name as in the Camera, but under the heading "File Info 2".

Spotlight finds information in the Image Comment field but not in Copyright or Artist.

Clearly Nikon's own software is the best option to view data entered using Nikon's cameras. If you happen to be somewhere without access to Nikon's software, you can look for dedicated EXIF readers that will fine at least some of the data. For example the free little application EXIF-O-Matic, is able to display the fields Artist and Copyright.
