camera obscura

Examples of camera obscura in the following topics:

• Development of Photography

  • Camera photography was invented in the first decades of the 19th century.
  • Camera photography was invented in the first decades of the 19th century, and even at this early point, it was able to capture more information, and with greater speed, than painting or sculpture.
  • In the 5th century BCE, before the first camera was ever invented, Chinese and Greek philosophers described the "pinhole camera," a lightproof box with a tiny hole in one side that allowed light to pass through and project an inverted image one side.
  • The camera obscura is a version of the pinhole camera, and was often used as a tool by artists such as Leonardo Da Vinci as a technique to create paintings.
  • The process of photography was effectually engaged in creating a permanent image from the process outlined originally by the camera obscura.

• History of Photography

  • While photography is the result of several technical discoveries, from the concept of the pinhole camera to the use of camera obscura, the history of photography really begins with the ability to create permanent images.
  • Around the year 1800, Thomas Wedgwood made the first known attempt to capture the image in a camera obscura by means of a light-sensitive substance.
  • Exposure times in the camera, although somewhat reduced, were still measured in hours.
  • Paper with a coating of silver iodide was exposed in the camera and developed into a translucent negative image.
  • In July 1888 Eastman's Kodak camera went on the market.

• Photography: Recording an Image

  • The camera (or 'camera obscura') is a dark chamber from which, as far as possible, all light is excluded except the light that forms the image.
  • The purpose of a camera - whether it is a digital or film camera - is to project light onto a surface that will capture an image.
  • Traditionally this is not a camera control, but rather the type film being used.
  • However in digital cameras, the ISO equivalency is controlled in the camera itself, as there is no real film being used.
  • Digital cameras use an electronic image sensor based on light-sensitive electronics.

• Photography in America

  • The history of photography has roots in antiquity with the discovery of the principle of the camera obscura, and the observation that some substances are visibly altered by exposure to light.
  • In the mid-1820s, Nicéphore Niépce succeeded, but several days of exposure in the camera were required and the earliest results were very crude.
  • Niépce's associate Louis Daguerre went on to develop the daguerreotype process, the first publicly announced photographic process, which required only minutes of exposure in the camera and produced clear, finely detailed results.
  • In July 1888 Eastman's Kodak camera went on the market with the slogan "You press the button, we do the rest".

• Other Means of Representing Space

  • In photography, for example, altering the position of the camera can change the image so that the subject has fewer or more distractions with which to compete .
  • This may be achieved by getting closer, moving laterally, tilting, panning, or moving the camera vertically.

• Mantua

  • Under Francesco II, the famous Renaissance painter Andrea Mantegna worked in Mantua as the court painter, producing some of his most outstanding works, including the Camera degli Sposi ("bridal chamber").

• Photography in the Latter 20th Century

  • Published in Camera Work, No. 20, 1907, is a good example of a Pictorialist photograph due to its soft focus and painterly aesthetic.

• Modern Life

  • Photography was gaining popularity, and as cameras became more portable, photographs became more candid.

• Motion

  • The reason for the wagon wheel effect is that motion-picture cameras conventionally film at 24 frames per second.
