terraPin Bijou 6 x 4.5 Pinhole Camera

thingiverse

Little sister to other terraPin pinhole cameras, Bijou takes a 6 x 4.5 vertical format in a proper 4:3 ratio for photography. Simply rotate her sideways on your tripod to switch to landscape orientation. The terraPin slider joint makes it easy to adjust the camera size or create new sizes with just a few tweaks. This model has become incredibly popular among pinhole photographers. Now, with the new Sidewinder body, Bijou offers both Portrait and Landscape formats! This new addition brings sixteen exposures per roll of 120 film for ultimate flexibility. The terraPin Bijou features an impressive 6 x 4.5 frame (56 x 41.5 actual) designed specifically for a 0.26 mm pinhole diameter at f/135, which translates to a "35mm focal length" of 35 mm. The resulting image captures a vast horizontal angle of view of 61.32° and a wide vertical angle of view of 77.32°. For a peek at the latest photographs taken with terraPin cameras, click here!

In addition to the new body style, the Bijou model includes improved film loading mechanics for proper indexing on a roll of 120 film. Make sure to load the film on the left side and wind it up on the right to achieve precise results. As with other terraPin cameras, exposure calculations are simplified at f/135, allowing users to get professional-looking results similar to the P6*6 or the terraPin 6X6 models in their 35mm focal length versions. While vignetting may be present, it will be minimal compared to the terraPin 6X9 due to its smaller film size. The sliding shutter on the Bijou model boasts a sturdy new design that is less likely to get damaged during transport than other swinging shutters commonly used in pinhole cameras. For those who prefer to trip their shutter from the left side, the extension can be flipped easily by 180 degrees. A note on technical aspects: terraPin was designed using powerful tools like Tinkercad and OpenSCAD, ensuring its robust structure. A shoutout is extended to Thingiverse citizen Aubenc for his generous contribution of the Knurled Surface Library v2, which greatly enhanced the overall aesthetic appeal of my cameras!
