Adding face tags to photos of friends and family in Phototheca is simple. Phototheca’s face recognition scans your photos for images with people and catalogs when a face is detected. If a face is new to Phototheca, the face goes into the Unnamed tab of People View. There you will have stacks of photos where the same face appears. As you tag people in photos, the app will learn specific faces and match untagged faces with previously identified people.
