Episode Details

A Catholic priest (Fr Philippe Dalleur) and youtuber (Ethan Muse) have argued that shadows in photographs taken at Fatima in 1917 provide scientific evidence for extraordinary sources of light in the sky. So I spent more than 100 hours investigating the claim, since my entire job revolves around working with cameras and lighting as a cinematographer.
