    Photography is the process of recording pictures by means of capturing light on a light-sensitive medium, such as a film or electronic sensor. Light patterns reflected or emitted from objects expose a sensitive silver halide, based chemical or electronic medium during a timed exposure, usually through a photographic lens in a device known as a camera that also stores the resulting information chemically or electronically.

    The word "photography" comes from the French photographie which is based on the Greek words , meaning "drawing with light." Traditionally, the product of photography has been called a photograph, commonly shortened to photo.

    :hugs:The camera is the image-forming device, and photgrphic film or a silicon electronic image sensor is the sensing medium. The respective recording medium can be the film itself, or a digital electronic or magnetic memory.
    Photographers control the camera and lens to "expose" the light recording material (such as film) to the required amount of light to form a "latent image" (on film) or "raw file" (in digital cameras) which, after appropriate processing, is converted to a usable image. Modern digital cameras replace film with an electronic image sensor based on light-sensitive electronics such as charge coupled device (CCD) or complimentary metal oxide semiconductor (CMOS) technology. The resulting digital image is stored electronically, but can be reproduced on paper or film.;):thumbup:

    All photography was originally monochrome, or black and white. Even after color film was readily available, black-and-white photography continued to dominate for decades, due to its lower cost and its "classic" photographic look. In modern times, black-and-white has mostly become a minority art form, and most photography has become color photography.
    Many photographers continue to produce some monochrome images. Some full color digital images are processed using a variety of techniques to create black and whites, and some cameras have even been produced to exclusively shoot monochrome. i will show u one black and white picture...see below

    here color photography is been explained


    Color photography was explored early. Early experiments in color could not fix the photograph and prevent the color from fading. The first permanent color photo was taken in1861 by the physicist James Clark Maxwell

    One of the early methods of taking color photos was to use three cameras. Each camera would have a color filter in front of the lens. This technique provides the photographer with the three basic channels required to recreate a color image in a darkroom or processing plant.

    Digital imaging uses an electronic image sensor to record the image as a set of electronic data rather than as chemical changes on film. The primary difference between digital and chemical photography is that analog photography resists manipulation because it involves film, optics and photographic paper, while digital imaging is a highly manipulative medium. This difference allows for a degree of image post-processing that is comparatively difficult in film-based photography and permits different communicative potentials and applications.a picture of digital camera

    The camera has a long and distinguished history as a means of recording phenomena from the first use by Daguerre and Fox-Talbot, such as astronomical events (eclipses for example) and small creatures when the camera was attached to the eyepiece of microscopes . The camera also proved useful in recording crime scenes and the scenes of accidents .The set of accident photographs was used in the subsequent court of inquiry so that witnesses could identify pieces of the wreckage, and the technique is now commonplace in courts of law.

    The art and science of Food Photography is a specialisation in general commercial photography. Food and Drink Photography is one of the most challenging aspects of still life work. The main areas of food photography are: Editorial for Magazine and Books on food including but not limited to cook books, advertising and packaging design1.

    Thank you, Shaun. We have looong waited for someone to give us all these explanations, since none of us know how to use the www to look for these pieces of information ourselves... As you can see, by the way, I put your 4 or 5 separate threads together to one, so our forums stay a little more uncluttered. OK? And then changed the title accordingly. Right?

    I like the special reference to food photography, as food plays an important part in my life (as you would expect for a pot-bellied pig)!

    The only thing I find particularly disconcerting about ShaunX's posts is that talks about himself in the third person.

    True, true, true... But I just had a cup o'Joe and felt inclined to make it rhyme. :lol:
