I recently subscribed to Lenswork based on recommendations here and elsewhere. And I just listened to one of the podcasts: "My Favorite F-Stop." It's... interesting. It starts with a basic reasoning for picking f/8.0. Then the podcast spirals into a largely incoherent rambling of unrelated and disparate subjects including Pythagorean mathematics, metaphysics and an exhausting stream-of-consciousness soliloquy, and climaxes in the most incongruous completion of a narrative circle.
