Protect your images by adding Copyright metadata to them as you import them
Using the Metadata tool in the Apply During Import panel you can add copyright data to your images as you import them. If you write this data automatically into every image you will ensure that your images always include your contact details and copyright information.
To create a preset to use, from the Metadata drop-down list choose New and create a copyright preset that has, at the minimum IPTC Copyright and IPTC Creator data entered. Type a name for it and save it and select it in the Metadata list.
As this data will be added to all images only provide data that is applicable to every image such as your copyright information, copyright status, rights, usage terms and details about you and how you can be contacted. Leave out image specific data such as what the image contains and its location for example as this will be different for most images.
