elements such as dirt, scratches, or signs of aging. People use raster graphic editors to restore digital images or to add or replace torn or missing portions of a physical photograph. Unwanted color tones are removed, and the contrast or sharpness of an image can be altered to restore the range of contrast or detail believed to be in the original physical image. Digital image processing techniques included in image enhancement and image restoration software are also used to restore digital photographs.
214:) produces a unique image, as there is no negative created. After coating a copper plate with light-sensitive silver iodide, the plate is exposed to an image for over 20 minutes and then treated with fumes from heated mercury. The longer the exposure to light, the more mercury fumes are adsorbed by the silver iodide. After the plate is washed with salt water, the image appears, reversed. This was the earliest photographic process to gain popularity in America. It was used until around 1860. 4047: 267:, was the most common kind of print in the latter half of the nineteenth century. Beautiful sepia gradation images were created by using albumen and silver chloride. The surfaces of prints made with this process were glossy because of the egg whites which were layered heavily to prevent the originally thin prints from curling, cracking, or tearing easily. This type of print was especially common for studio portraits and landscape or stereoviews. 591:, along with pollution, can cause fading and discoloration of silver images and color dyes. Higher temperatures cause faster deterioration: the rate of deterioration is approximately doubled with every temperature increase of 10 Â°C. Fluctuations in temperature and relative humidity are particularly damaging, as they also speed up chemical deterioration and can cause structural damage such as cracked emulsions and warped support layers. 4058: 884: 962:, treatment is "the deliberate alteration of the chemical and/or physical aspects of cultural property, aimed primarily at prolonging its existence. Treatment may consist of stabilization and/or restoration." Stabilization treatments aim to maintain photographs in their current condition, minimizing further deterioration, while restoration treatments aim to return photographs to their original state. 36: 439:
film stored in darkness is largely responsible for excellent color footage of World War II, for example. It has been calculated that the yellow dye in Kodachrome, the least stable, would suffer a 20% loss of dye in 185 years. This is because developed Kodachrome does not retain unused color couplers. However, Kodachrome's color stability under bright light, especially during

Both factors may lead to color changes over time. The three dyes, cyan, magenta, and yellow, which make up the print may fade at different rates, causing a color shift in the print.

UV-absorbing sleeves can be used to filter out damaging rays from fluorescent tubes and UV- absorbing sheets can be placed over windows or in frames. Low UV-emitting bulbs are available.

Relative humidity should be maintained at 30–50% without cycling more than +/- 5% a day. The lower part of that range is best for "long term stability of several photographic processes".

Paper enclosures protect objects from light, but may result in increased handling for viewing. Paper enclosures must be acid-free, lignin-free, and are available in both buffered (alkaline, pH 8.5) and unbuffered (neutral, pH 7) stock. Storage materials must pass the ANSI Photographic Activity Test

In addition to fading, silver-based images are prone to silver mirroring, which presents as a bluish metallic sheen on the surface of the photograph or negative and is caused by oxidation, which causes the silver to migrate to the surface of the emulsion.
