Happy World Pinhole Day!

Technically, camera obscura, not pinhole, but... ever since I saw the thread on Abelardo Morell that Tanguera created, I've wanted to do this. The pinhole is a 3mm hole in a piece of tin foil on the window.

In any case, the clarity and sharpness of the projected image speaks well for large format imaging.


I used the usual calculations for determining the pinhole size, assuming a 10 foot focal length, and it came to 3mm. My rough calculation based on camera settings, exposure, and the settings of the camera turned around and pointed directly at the yard is that this is f/2000ish. When I was shooting, once my eyes adjusted I could clearly see the leaves on the bed, but the blue car was just a dim blue blur, and I couldn't see the hedge across the street at all.
