Lightroom - Set Copyright Data On Import

During the Import process, you can set up your Copyright info, and any other Metadata that you use on all images as a preset.

Step 1 - During an import, head to the 'Apply During Import' section and select the Metadata pull-down menu and then select 'New...'. 

Step 2 - In the 'New Metadata Preset' window give your preset a name and set up all your copyright information in the IPTC Copyright and IPTC Creator sections. Then select 'Create'. 

From now on, whenever you do an import, you can select your copyright preset, and it will be applied to all your images.
