Yes, photography is about cameras, lenses, the shot, the location, the moment, and the inspiration, but it is also about protecting your art. As Bill is moving from in person sales to on-line sales, I felt it was necessary for him to take the time to insert metadata into each photo. Adding metadata to photos has benefits beyond copyrighting, it allows the photographer to effectively catalog their work, making each desired photo easier to find without relying on memory. If the photographer can't find the photo, the viewer may not be able to find it, either.
In the video above, Aaron Nace gives clear instruction on the steps to take to add metadata to photos in Lightroom. The 14 minutes and 21 seconds will be time well-spent. Information and instructions are included in the description of the video, but I'm including some things here for easy reference.
