Digital images come with a method of adding in additional information called Metadata. This allows you to add such things as copyright notices, model release info, description and caption, publication and location info and loads more. All of this is saved with the image and available to any program that can access the metadata making it a great way to add useful content to the image file. Here is how to access and update the metadata for an image using Adobe Photoshop Elements.
