Adding copyright data

The EOS 5D Mark II and EOS 50D cameras offer a new feature that allows you to input a copyright notice and your name. This information is added to the camera's EXIF shooting data (it isn't watermarked into an image), and can be viewed using Canon Digital Photo Professional software, as well as third-party browsing/image editing programs such as Photoshop. To input this information connect your camera to your computer via a USB cable. Using EOS Utility software, navigate to the Camera Settings section and type in the information you want to appear with each image and then upload this information into the camera. Once installed, you can view this information on the EOS 5D Mark II or 50D menu at Set-Up Menu 3 > Clear Settings > Press INFO. button. It's not possible to set or change this information using the camera alone. You can delete the information using the Clear Settings menu option by selecting Delete Copyright Information.
