The terraPin OSKAR Tuxedo 6X9 pinhole camera is easy to print and assemble, requiring but a single lock nut and bolt for the shutter and a flanged 1/4-20 nut for the tripod mount. The 29 mm ‘focal length’ provides for a wide angle (approx. 110 degrees) and just a bit of optical vignetting at the corners of the 6X9 frame, for a classic pinhole look. OSKAR is designed for a pinhole diameter of 0.23 mm, but that’s not a critical dimension. Exposure charts for a variety of films are included in the Thing Files.
