  2. The history of photography began with the discovery of two critical principles: The first is camera obscura image projection, the second is the discovery that some substances are visibly altered by exposure to light. [2]

    history of photography, method of recording the image of an object through the action of light, or related radiation, on a light-sensitive material. The word, derived from the Greek photos (“light”) and graphein (“to draw”), was first used in the 1830s.

    As a means of visual communication and expression, photography has distinct aesthetic capabilities. In order to understand them, one must first understand the characteristics of the process itself. One of the most important characteristics is immediacy. Usually, but not necessarily, the image that is recorded is formed by a lens in a camera. Upon exposure to the light forming the image, the sensitive material undergoes changes in its structure, a latent (but reversed) image usually called a negative is formed, and the image becomes visible by development and permanent by fixing with sodium thiosulfate, called “hypo.” With modern materials, the processing may take place immediately or may be delayed for weeks or months.

    The essential elements of the image are usually established immediately at the time of exposure. This characteristic is unique to photography and sets it apart from other ways of picture making. The seemingly automatic recording of an image by photography has given the process a sense of authenticity shared by no other picture-making technique. The photograph possesses, in the popular mind, such apparent accuracy that the adage “the camera does not lie” has become an accepted, if erroneous, cliché.

    This understanding of photography’s supposed objectivity has dominated evaluations of its role in the arts. In the early part of its history, photography was sometimes belittled as a mechanical art because of its dependence on technology. In truth, however, photography is not the automatic process that is implied by the use of a camera. Although the camera usually limits the photographer to depicting existing objects rather than imaginary or interpretive views, the skilled photographer can introduce creativity into the mechanical reproduction process. The image can be modified by different lenses and filters. The type of sensitive material used to record the image is a further control, and the contrast between highlight and shadow can be changed by variations in development. In printing the negative, the photographer has a wide choice in the physical surface of the paper, the tonal contrast, and the image colour. The photographer also may set up a completely artificial scene to photograph.

    The most important control is, of course, the creative photographer’s vision. He or she chooses the vantage point and the exact moment of exposure. The photographer perceives the essential qualities of the subject and interprets it according to his or her judgment, taste, and involvement. An effective photograph can disseminate information about humanity and nature, record the visible world, and extend human knowledge and understanding. For all these reasons, photography has aptly been called the most important invention since the printing press.

    The forerunner of the camera was the camera obscura, a dark chamber or room with a hole (later a lens) in one wall, through which images of objects outside the room were projected on the opposite wall. The principle was probably known to the Chinese and to ancient Greeks such as Aristotle more than 2,000 years ago. Late in the 16th century, the Italian scientist and writer Giambattista della Porta demonstrated and described in detail the use of a camera obscura with a lens. While artists in subsequent centuries commonly used variations on the camera obscura to create images they could trace, the results from these devices depended on the artist’s drawing skills, and so scientists continued to search for a method to reproduce images completely mechanically.

    In 1727 the German professor of anatomy Johann Heinrich Schulze proved that the darkening of silver salts, a phenomenon known since the 16th century and possibly earlier, was caused by light and not heat. He demonstrated the fact by using sunlight to record words on the salts, but he made no attempt to preserve the images permanently. His discovery, in combination with the camera obscura, provided the basic technology necessary for photography. It was not until the early 19th century, however, that photography actually came into being.

    • Before Photography. The first "cameras" were used not to create images but to study optics. The Arab scholar Ibn Al-Haytham (945–1040), also known as Alhazen, is generally credited as being the first person to study how we see.
    • The First Photographers. On a summer day in 1827, French scientist Joseph Nicephore Niepce developed the first photographic image with a camera obscura.
    • Negative to Positive Process. The drawback to daguerreotypes is that they cannot be reproduced; each one is a unique image. The ability to create multiple prints came about thanks to the work of Henry Fox Talbot, an English botanist, mathematician and a contemporary of Daguerre.
    • Other Early Processes. By the mid-1800s, scientists and photographers were experimenting with new ways to take and process pictures that were more efficient.
  3. Oct 9, 2023 · A few years after the invention of the daguerreotype, William Henry Fox Talbot devised the first photographic method that enabled the reproduction of images from a single negative image. This method was called the calotype method, which quickly became one of the most widely-used photographic processes of the mid-19 th century.

  4. Sep 27, 2024 · The finest daguerreotypes in Britain were produced by Antoine Claudet, who opened a studio on the roof of the Royal Adelaide Gallery in June 1841. He was responsible for numerous improvements in photography, including the discovery that red light did not affect sensitive plates and could therefore be used safely in the darkroom.

  5. The astonishingly precise pictures they saw were the work of Louis-Jacques-Mandé Daguerre (17871851), a Romantic painter and printmaker most famous until then as the proprietor of the Diorama, a popular Parisian spectacle featuring theatrical painting and lighting effects.

  6. Sep 11, 2024 · The calotype negative and salt-print positive were the most practical of the two pioneering processes. They were cheaper to make and most importantly could produce multiple copies. The pioneering Scottish photographers Hill & Adamson used these methods very effectively and almost exclusively.
