How Photographers Can Go Retro With Pinhole Cameras
Although the concept behind pinhole cameras --an inverted image passing through a very small hole into a light-proof chamber-- has existed since the 11th century, it was only until 1850 that a Scottish scientist by the name of Sir David Brewster took the first photograph using this technology.
The pinhole camera is basically a sealed box in which a piece of film is placed. Light enters the box through a tiny hole and exposes an image onto the film. As basic as that. Due to its simplicity a pinhole camera can be constructed from a shoe box, cereal box, matchbox, coffee can, oatmeal can, you name it. Examples range from the fairly expensive --birch wood cameras with $450 price tags-- to the bizarre --a human skull with a pinhole drilled into the forehead and film placed inside the cranium.
Technical Considerations For Pinhole Cameras
There are several factors that determine the kind of image we will get, and how much time we will need to invest into it. The smaller the hole, the sharper the image will be, although exposure time will be longer. Exposure times of several hours are not unheard of, although faster films may cut exposure times down to seconds or minutes. The focal length is determined by the distance between the pinhole and the film plane. A shorter distance, using a matchbox camera for example, will result in a wide angle field of view, while putting pinhole and film on opposite sides of a can of Pringles will give you a telephoto field of view. There is no need to focus, since depth-of-field is infinite on pinhole cameras.
The technical considerations mentioned above are precisely what do-it-yourself photographers find most interesting about pinhole cameras. The satisfaction of building a camera with your own hands and experimenting with different film speeds, pinhole diameters, camera sizes, exposure times and other variables is hard to obtain any other way.
Products To Help You Build A Pinhole Camera
Any of the following items will have you shooting pinhole images in no time. You decide how deep you want to dive into the building process. From making a camera out of cardboard to leveraging your existing digital equipment with a minimum of fuss.
