Camera Obscure, from a manuscript of military designs, Illustration of camera obscura from “Sketchbook on military art, including geometry, fortifications, artillery, mechanics, and pyrotechnics,” possibly Italian, c. Library of Congress.
“Kaiju” is a Japanese word that means “monster.” It refers to a genre of tokusatsu, or special effects entertainment. Kaiju films typically feature monsters of all kinds and the monsters are most often laying siege to a major Japanese city. Or, they’re fighting other monsters. Think Godzilla and Megalon, for example. Schlemmer grew up watching Kaiju movies and his favorite monster was Gamera, a rocket-powered flying turtle beast. And that’s the inspiration for the camera. In his words:
“The terraPin Kaiju is a giant, mutant pinhole Gamera!”
What’s a pinhole camera, though? It’s the most basic kind of camera there is. It is a variation on the camera obscura (in Latin that’s “dark chamber”), the earliest camera–but smaller and super minimalist. It’s an optical device that consists of a box (larger ones can even be entire rooms) with a hole in one side of it. Light from a scene outside of the box passes through the hole and strikes an interior surface. There it is reproduced upside down but with the color and perspective of the scene preserved. The image can be projected on light-sensitive paper or can be traced by hand onto a piece of paper. Exposure time can range from about five seconds to several hours. The best photos are of static scenes.
Schlemmer’s Pinhole Gamera uses 120 film, which is good for still photos. He shared several examples of photos he’s taken with it and they are surprisingly good–although none (so far!) capture the kind of creatures for whom the camera is named.
Some finishing of the 3D printed parts is required to ensure that the pieces fit together properly as, it probably goes without saying, even the smallest amount of light that gets in from somewhere other than the pinhole is unwelcome.
Once you’ve made your own Pinhole Gamera, you’ll want to refer back to the Thing page for Schlemmer’s instructions for using the device, including loading the film onto the spools and winding it. He’s more than happy to respond to questions as well via the comments section so that others can benefit from the Q&A as well.
According to Schlemmer, it’s his “mission to share and promote open source cameras and related parts created with CAD applications and 3D printing.” We love the way that this camera, the Pinhole Gamera, combines the latest technology–3D design and printing–with the long-standing technology of the first, rudimentary camera.
