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 can now be downloaded free of charge from my website. The book 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. [Go to page >>]

Camera builders

Building your own camera can be a very rewarding experience. Quite a few people have built their own large format camera, monorail or flatbed, simple or elaborate. I have collected a number of links to amateur camera builders. If you are considering building a camera, some of those links may help you getting started. You will also find some links to pages about restoring or modifying cameras. [Go to page >>]
