I discovered that Lightroom wasn’t automatically applying my copyright information on a recent import, and I need to identify only the images that are missing it. I can’t just apply one copyright preset to everything because my library includes different years and a few different copyright owners. I tried the Library Filter with Text and Metadata, but I couldn’t find a practical way to isolate images where the copyright field is missing or not set. Is there a way in Lightroom to find or group photos whose copyright status is not marked as copyrighted?
