View camera information


Basic view camera terminology

A view camera is a large-format camera in which the lens forms an inverted image on a ground-glass screen directly at the film plane. The image is viewed, composed, and focused, then the glass screen is replaced with the film to expose exactly the same image seen on the screen.[1]

This type of camera was developed during the era of the daguerreotype[2] (1840s–1850s) and is still in use, some using drive mechanisms for movement (rather than loosen-move-tighten), more scale markings, and/or more spirit levels. It comprises a flexible bellows that forms a light-tight seal between two adjustable standards, one of which holds a lens, and the other a ground glass or a photographic film holder or a digital back.[3] There are three general types: the rail camera, the field camera, and those that don't fit into the other categories.

The bellows is a flexible, accordion-pleated box. It encloses the space between the lens and film, and flexes to accommodate the movements of the standards.[4]: p. 34  The front standard is a frame that holds the lensboard, to which the lens (perhaps with shutter) is attached.

At the other end of the bellows, the rear standard is a frame that holds a ground glass plate, used for focusing and composing the image before exposure—and is replaced by a holder containing the light-sensitive film, plate, or image sensor for exposure. The front and rear standards can move relative to each other, unlike most other camera types. Whereas most cameras control only the distance of the plane of focus from the camera, the view camera can also adjust the orientation of the plane of focus, and perspective control. The camera is normally used on a tripod support.
