Hello all, I've been using iphoto and the Photos app for the past many years to keep an inspiration library of design and images that I like. Right now, all the photos/images live in a folder but are pretty much untagged and have no keywords associated with them. I'd like to change that so I can make that database searchable. Any tips or tools you can recommend for batch tagging within the Photos app? I've got literally thousands of images to get through. I use lightroom for my actual photography work and am familiar with the keywording functionality there, but would prefer to keep all my inspiration images in Photos so that it syncs with my ios devices.
