Transcript of Analogue Photography Redux
Building the Pinhole
Camera from Simple
a cardboard box
2 file cards
A small pinhole lets in a narrow beam from each point in a scene. The beams travel in a straight line, so light beams from the bottom of the scene hit the top of the piece of film. If the box is completely dark the light coming through the pinhole will make
an inverted or upside down
image on the film. What You'll Need Pinhole Camera 'How-to'
1. Remove the plastic lid from the candboard box and paint the inside black with acrylic paint.
2. In the center of the box's side, open a 0.5 X 0.5 cm round hole that is cut out with your x-acto knife. Cut the same size hole into your file card. This hole will act as your "lens".
3. Cut another 0.5 X 0.5 cm round hole into the piece of cardboard about 1/2 the size of the file card. and attach it as shown in the picture left). 4. In a dark room with a safe light cut the photographic paper to fit on the opposite end of the hole you made. Put the lid back on and your camera is ready for exposure. You can use the filecard you cut out to keep the shutter closed by taping it over the foil. The shutter has to be light tight, but it does not have trigger quickly if exposures are long. Step by Step Building My Pinhole Camera A pinhole camera is the most basic type of camera: a light-tight box, a piece of film or photographic paper, and a small hole to let light in. How Do Pinhole Cameras Work? Pinhole camera made from Girlscout cookie box "The photographs in this exhibition, organized by the students in Art 163, are all made using very low-tech cameras. Most of the cameras used - many on display in this exhibition - are handmade, one-of-a-kind cameras. They are made from a wide range of materials: foam core board, oatmeal boxes, PVC pipes, wood, tin cans, Legos, and whatever else the maker could make light tight. Some cameras are from readily available designs, some are modified traditional cameras, and others are wholly from the imagination of the maker. Additionally, some of the cameras use multiple pinholes, while others use slits or a series of concentric rings to let in light, rather than the traditional single pinhole.

history of the Camera Obscura A lens lets through lot more light into the camera than a tiny hole, and so a pinhole camera requires much longer exposure times. This type of camera also provides almost infinite depth-of-field, but the focus of the pinhole image is much sharper at the centre of the image and becomes fuzzy towards the edges. The Science of Taking
Pictures with a Pinhole Camera
Visit the website: Worldwide Pinhole Photography Day was established to celebrate the joy of simple creativity using the medium of lensless photography. Worldwide Pinhole Photography Day For any focal length there is an optimal pinhole diameter for image sharpness.
Generally a smaller pinhole will produce a sharper image than a larger one. If the pinhole gets too small, the image becomes less sharp because of diffraction Pinhole Images Lens Images What Do Pinhole Camera Pictures

A lens gathers a lot more light on its large surface
than a tiny hole, and so a pinhole camera requires much
longer exposure times. It also provides almost infinite
depth-of-field, which enables images that are in focus from a shortened foreground to the back. A pinhole camera is basically a box with a tiny hole in one side and some film or photographic paper on the opposite size. This collage tells the story of an avid digital photographer and gizmo fanatic who went lo-tech in a summer photo course.
When I took Alternative Photographic Processes, I put away my Nikon DX Series cameras, autofocus lenses, assorted computerized accessories, hd video recorder and retired my trusty Photoshop CS4.
Our course covered hand-coated paper, photograms, photomontage and solarization, along with pinhole techniques.
Unfortunately, we did not document our camera-building projects and image making from this part of the class--too busy building and experimenting--so this story is a reconstruction intended to get my fellow students interested in exploring this highly instructive analogue technology. I was surprised at the amount of optics and math knowledge that was needed to build a pinhole camera that would produce consistent exposures. My basic shoebox design had to be re-fitted at least 4 or 5 times before a passably balanced picture showed up on the photo paper. Most of my pinhole images were of studio props and they concentrated on controlling technical variables such as camera mechanics, focal length and exposure. The images in this story are far more artistic than those we made, and they properly display the potential of this format. Student classes that spend a whole term on pinhole techniques can produce some excellent and responsive handmade cameras. Cameras have been made of sea shells, many have been made of oatmeal boxes, coke cans or cookie containers, at least one has been made of a discarded refrigerator. As early as the tenth century, experiments with pinholes were made, and in the Renaissance, the camera obscura was a popular form of entertainment and also a tool for artists to better understand perspective. Pinhole photos have a great 19th C quality that was further enhanced by the hand development and toning techniques that we learned in class.
