PHOTOGRAPHIC PERSPECTIVE has become the most popular form of optical, technical, or instrument perspective, partly because of its ease of use and the rapidity with which perspective images can be taken (compared to the slow process of producing artistic drawings/paintings).
Photographical Perspective
However, the reproducibility, portability, ease of storage, and communicability of film/digital images are major advantages, along with the inherent image accuracy of these media over hand-drawn art. Important technologies related to photography include the camera obscura, developed in the 5th century BC; the lens, from the 13th century; and photochemistry, from the 18th century.
Modern photography first emerged in 1826-7 in the form of a technique invented by Joseph Nicéphore Niépce called Heliography, which produces one-of-a-kind perspective images (of spatial reality) on metal plates treated with light-sensitive chemicals. By the early 1840s, early Daguerreotype photographic images required an exposure of around twenty minutes.
The past century saw the invention of new kinds of photographic film cameras, which recorded images of objects with no human intervention beyond pressing a button. Subsequent developments, including Flexible-Roll-Film, Colour-Film, Single- Lens-Reflex, Instamatic, and Polaroid Cameras, among others, provided new methods and processes that further enhanced photographic techniques, from speed to malleability and image-processing in modern digital photography.
In a sense, the photographic camera marked the logical conclusion of a trend linking apertures in a camera obscura and images that had emerged a thousand years earlier.
Window Principle
Photography provided a physical demonstration that the window principle (ref. picture plane / directing plane) of perspective was a function of objective geometry, independent of a painter’s subjective interventions. In any case, photographic cameras do not employ an overt perspective window(s) to establish the viewpoint, viewing angle, and field of view, etc., and because these factors are all fixed instantly when the camera button is pressed.
Theoretically, photography promised a one-to-one correspondence between the original object and image. This principle has proven of great interest to architects. In other fields, photographic surveying techniques provided accurate matching/indexing methods essential to map-making.
With the rise of photography in the latter nineteenth century, correspondence questions arose anew: whether the eye perceives photographic space in the same way as physical space. In any case, the advent of digital cameras and the Internet in the 1990s brought many dramatic changes to photography, enabling digital images to be rapidly created (in vast numbers), shared, processed, linked together, and possibly integrated into a single image-space, as in the Google Maps system.
