Color photos can create images that are either positive (ie have the same colors as the reality) on transparent film for use in a slide projector, or as negative (which is inversely color ratio) to be used to create positive enlargements on special photo paper. The latter form is the most common for developing color film (Columbia SC photography). Film-based photography has been difficult for photographers who worked far from the photo lab, especially after television news photographers were being pushed to deliver images faster. Therefore, news photographers previously had their own printing lab and ways to convert the photos to transfer them via telephone.
Some digital full color photos are processed through different techniques to create black and white photographs, but there are also special cameras for black-and-white photographs. Usually, special movie when to take black and white photographs. Many black/white photographs did not use black as a contrasting color to white, but sepia, a brownish color.
The market for photographs showing the truth of anadage that "images are worth a thousand words." Newspapers, magazines, web agencies, advertising agencies and other companies pay for images. There is even photographic agencies that sell archival images for use in newspapers, for example. One of the most famous photo agencies Magnum which is served ever since in 1947.
The main difference between digital photos and film-based variants is that analogue is more difficult to manipulate because it involves film, optics and photographic paper, while it is quite easy to manipulate digital images, which makes it easier for amateur photographers to take great pictures.
Because images are associated with the truth (the camera does not lie) - digital photos caused many ethical questions. Many photojournalists have expressed that they will not combine elements from different photos and claiming that they are real photographs. Therefore, several courts have stated that they do not accept digital images as evidence because they are easy to forge.
Digital photos have replaced film-based images, both in the private and professional market. In January 2004, Kodak announced that it would no longer manufacture the cameras used photographic film. There are also other types of photographs than the above. Some types require very special cameras and other peripherals, such as night photography (requires a tripod because of the prolonged exposure), infrared photos (special film and filters in front of the lens).
Underwater photos (waterproof body and wide-angle lens because of the water's refraction degree) and stereo photography (special camera dual lens or special adapter that splits the image into two parts, for example, to create 3D effects). An early image manipulation where Vladimir Mayakovsky's married mistress, Lily Brik faded out of picture for political reasons.
The technique of color photographic images developed in the mid 1800's. Early experiments had problems with fixing the images and to prevent colors from fading. One of the early methods for taking color images involved use of three cameras. Each camera had a color filter in front of a lens, giving the three fundamental channels to reproduce a color image in a dark room or the developing lab. The Russian photographer Sergey Prokudin-Gorsky developed another technique with three color plates taken in quick succession. From ancient times it was known that certain substances which silver salts and asphalt, changed by the influence of light, and several had experimented with it; but a user-friendly technique first developed by two Frenchmen, Niepce and Daguerre.
