It was a dull, cloudy day out, so even with some lights turned on, this interior shot was exposed for about 9,000 seconds; that’s two and one-half hours. 🙂 The aperture is 0.2mm and the focal length is 0.9″ for an f-stop of about 114. My collection of first editions of illustrated copies of Voltaire’s Candide and E. A. Poe’s The Adventure of Arthur Gordon Pym are hardly legible. 😦
This is the image I should have taken with my pinhole camera yesterday at The Cloisters! But it was made with my iPad.
