When I searched YouTube for videos on the healing power of black and white photography, I got no hits. But there is a groundswell of how-to tutorials on restoring antique photos, including this one. Suzanne Allen uses a photo of her grandmother to demonstrate the technique but does not once mention anything about her subject or why she chose to retouch this particular photo.

Fort Worth Library also presents a workshop on the Conservation, Preservation, and Restoration of antique photos but again it is not part of a community-building process or healing process, like Imagine Antigonish.
