Color Photography

Color Photography uses media that is capable of producing colors chemically during a processing phase. The first known permanent color photograph was produced by James Clerk Maxwell in 1861. The first modern color film, known as Kodachrome, was created by Eastman Kodak Company in 1935. However most modern color technoglogy uses Agfacolor, which was introduced to the public in 1936. Also, instant color film was produced by Polaroid in 1963.Color photography uses two different kinds of film; negative and reversal. Negative film forms a negative image, also known as a color-reversed photo, when exposed and then made permanent during development. At the end of the process, the photograph is then developed onto photographic paper to form a positive image.
The other type of film used in color photograph is reversal film. This kind of film, also known as slide film, forms a negative film as well when exposed and is then reversed during developing. The photograph can then be projected.In addition to types of film. Color photography has two different types of color systems. The first, additive, uses the most common set of primary colors; red, green, and blue. This system uses colored lights to add the color to photographs. The other system uses a subtractive color system. In this system, colors are subtracted from white lights by dyes or pigments. The most common set of primary colors in this system is cyan, magenta, yellow, and black.
