First off is using a soft brush that can remove surface dirt on the print. Make sure to lightly brush the dirt off of the print. Damping cotton swabs or using a specialized cleaning pad to dry wipe the surface of the print is also another method to clean it. Remember to never wash photographs until the gelatin layer is dry and stables.
Color–color diagram. A color–color diagram is a means of comparing the colors of an astronomical object at different wavelengths. Astronomers typically observe at narrow bands around certain wavelengths, and objects observed will have different brightnesses in each band. The difference in brightness between two bands is referred to as an ...
In color photography, electronic sensors or light-sensitive chemicals record color information at the time of exposure. This is usually done by analyzing the spectrum of colors into three channels of information, one dominated by red, another by green and the third by blue, in imitation of the way the normal human eye senses color.
A color rendering index ( CRI) is a quantitative measure of the ability of a light source to reveal the colors of various objects faithfully in comparison with a natural or standard light source. Color rendering, as defined by the International Commission on Illumination (CIE), is the effect of an illuminant on the color appearance of objects ...

Cyan, magenta, and yellow are the three basic colors used for color reproduction. When these three colors are variously used in printing, the result should be a reasonable reproduction of the original, but in practice this is not the case. Due to limitations in the inks, the darker colors are dirty and muddied.
A chromogenic print, also known as a C-print or C-type print, [ 1] a silver halide print, [ 2] or a dye coupler print, [ 3] is a photographic print made from a color negative, transparency or digital image, and developed using a chromogenic process. [ 4] They are composed of three layers of gelatin, each containing an emulsion of silver halide ...
