This weekend I woke up inside an actual camera obscura. Our (hotel) bedroom had Velux roof window which was minimally opened. The tiny openings on the lower side of the window projected the neighboring scenery on our (white) bedroom walls.

The smaller the hole, the sharper the projected image is. You can even see the beer crates in front of the neighboring house.

All photos were taken handheld from the bed at ISO30.000 (or higher), so there is wee bit of noise. The photos also show the bed, door-handle and a radiator in the room.
