Book excerpt: How to Film Truth explores the history of documentary film as a search for truth by filmmakers, and a journey of discovery for subjects and audiences. This process, the act of documenting, exploring, and reflecting on our reality in all its created beauty, wonder, and mystery can itself be a devotional practice. The history can be seen as moving from actuality to ecstasy, from propaganda to empathy, and finally to confessional, emotional, personal, and communal healing.
