Pinhole Photography – History, Images, Cameras, Formulas

Pinhole image

Pinhole photography is lensless photography. A tiny hole replaces the lens. Light passes through the hole; an image is formed in the camera.
    Pinhole cameras are small or large, improvised or designed with great care. 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. Cameras have been cast in plaster like a face mask, constructed from beautiful hardwoods, built of metal with bellows and a range of multiple pinholes. Station wagons have been used as pinhole cameras – and rooms in large buildings. Basically a pinhole camera is a box, with a tiny hole at one end and film or photographic paper at the other.

Designing and Building a Large Format Camera

Grepstad large format camera

My book Building a Large Format Camera is an 85 page manual with instructions and plans for building a 4 x 5 inch monorail camera with friction focusing. The book has 30 step-by-step drawings, 23 sketches and 11 photographs, a wealth of references to relevant literature and numerous useful addresses in the US and Europe. Most drawings are to scale and may be scaled up for an 8 x 10 inch camera. The book is available by order direct from me. [Details >>]

Lanced in Light – Visible and Invisible
Infrared, Ultraviolet and X-Ray Photography

IR photograph We are lanced in light; and we move through light, shadows and darkness.
Visible light, infrared and ultraviolet radiation, and X-rays produce different kinds of fine art photography.

The phrase Lanced in Light was suggested to me by Larry Rubin's collection of poems with the same title (1967). In 1966–67 Larry Rubin was a Fulbright scholar at the University of Bergen, Norway, where I studied languages and literature.

Stones – Pinhole Prints 2007

Stone Stones are the theme of my new pinhole images. The pictures were made in 1992 and have recently been scanned. I used Ilford Multigrade III RC Deluxe (7 x 9½ in) for the negatives and contact printed on the same kind of paper.

Multimedia Pinhole Postcards

Electronic pinhole postcards reconcile old and new technology. Theories of pinhole-derived images are found in the ancient writings of Aristotle, Chinese philosopher Mo Ti, and Arabian mathematician Ibn al-Haytham (Alhazen). Later, artists like Leonardo da Vinci, Canaletto, Dürer and Vermeer used camera obscuras as drawing aids. From the 1850s pinhole cameras have been used for photography.

My electronic postcards (script by Sue Braiden):

Pinhole stamps
Rome: The Tiber, view towards the Ponte Cavour Rome: The Forum Prague: U Zlaté studně

My personal postage stamps with pinhole pictures from Rome and Prague (The Tiber, The Forum, The Golden Well). The Prague pinhole picture has been run through the fresco filter in Photoshop.
