The early experiments in color photo arts were tiresome; most of the undertakings needed long time exposures, usually in a number of hours until several days so that the colors of camera images may not fade so easily. In order to enhance quality of color photo, the photo experts below contributed applicable principles. 1. JAMES CLERK MAXWELL. As a physicist, Maxwell introduced the "separation of three colors" principle in 1855. This principle was first used in 1861. The rationale behind the principle, according to Maxwell, was to produce at least three individual black-and-white photos by using three different filters such as red, blue and green. At that time, most photographers were taught the most basic channels in producing color camera images. 2. LOUIS DUCOS DU HAURON. According to him, transparent photo images may be projected using similar filters. For instance, a color print image on a photo paper can be produced by simply superimposing carbon color prints of three different images using their complementary colors. This process is called "subtractive method" which introduced in the later part of 1860s. 3. SERGEI MIKHAILOVICH PROKUDIN-GORSKII. This Russian photographer expounded extensively on the technique in using color separation. He made use of a special type of camera which placed the filtered images over an oblong-shaped plate. Since the exposures of images weren't simultaneous, the resulting printed images looked like clearly- colored ghosts. 4. HERMAN VOGEL. The continuous progress of portrait photography was, in the meantime, obstructed due to the sensitivity of the photo elements used; said elements were mostly sensitive to red, blue and red. In 1973, however, Vogel introduced a very relevant procedure called "sensitization." This procedure enhanced the level of sensitivity of red, yellow and green. In effect, the long-time exposure requirement for color photos was significantly reduced to some extent. The resulting photos, therefore, were so much closer to commercial quality production. 5. THE LUMIRE BROTHERS. In 1907, these gentlemen brought to the world the very first color process called "auto-chrome." This process, as applied in professional corporate photography, proved to be commercially very successful since it incorporated into the autochrome plates some sort of mosaic filter made of dyed potato starch grains. This made the three-color elements to be captured as adjacent image fragments. </li><li> 3. 6. THE KODAK. In 1935, an integral tripack technology called "Kodachrome" was developed by Kodak. This technology allowed the capture of at least three hues in a specifically three-layered emulsion. The first layer recorded the green portion of the spectrum, the second layer recorded just the red area, while the third spectrum recorded only the blue part. 7. AGFACOLOR NEU. In 1936, Agfa introduced another technological breakthrough called "Agfacolor Neu." As early as during the manufacturing process, all color couplers were added into the layers of emulsion. The ultimate effect of this process was the simplification of the photo processing. These days, color photography technology remains very useful in professional photography, such as newborn photo arts and family photo arts. With the advent of digital photo technology, the color photo process becomes even more helpful. </li></ol>
