concept, rendered in the title of the article, is widely applied in the fields of science and practice, as astrophysics, production of various types of lamps and filters.The physical nature of the phenomena that characterize the color temperature, is that it creates an objective basis for the human perception of color.In a more complex interpretation, it shows the spectral structure of the radiation emitted from a particular source.As the eye color perception is largely determined by subjective characteristics of the human body, the nervous system, the parameters of the visual system, the objectification of the spectral properties of the scale of using special colors according to the temperature sources.
For example, the color temperature of the beginning of the visual perception of the human eye to hot substances or bodies is 800 K.
This indicator shows the degree of intensity of the radiation source within the optical range.Its value is measured in Kelvin.
According experimentally established standards, light the candle flame becomes visible when a temperature of 1500-2000 K, and the glow of a simple incandescent lamp of 40 watts becomes observable at 2000 K. In general, the color temperature of light bulbs is determined by their capacity and ranges from2000 K to 3000 K, for the most common consumers standards (40 - 200 W).The most common lamps used in kinovosproizvodyaschey Filming and technology, have a temperature of 3200-3250 K. The Sun when entering the horizon it seems if the color temperature is 3000 K, in the afternoon - 5000 K, but the clouds to be visible, must "warm "is already up to 5500 K.
Among climatic phenomena highest temperature has a clear winter blue sky with a temperature of 15,000 K, and the same phenomenon in the northern latitudes, where the color temperature can reach 20,000 K
most often happens when a person can estimate the figure is, of course, the use of various kinds of lighting fixtures, lamps equipped.Here, for example, is now widely used in the home and other areas of fluorescent lamps have a much higher temperature.According to the color temperature fluorescent lamp, depending on its other characteristics, can be from 2700 to 7700 K at its maximum impact.
setting the color temperature commonly used in photography and cinema.For example, any color film made entirely with fixed values of the color temperature.This is achieved by its high color quality.If you run a slide or negative shooting or shooting at longer focal lengths, you need a film in which the balance sheet is used color temperature - about 5600 K for daylight and 3200 K for the shooting in the evening.
Modern digital cameras also apply the balancing effect, but this is achieved by automatic adjustment of the fotoustroystva or preset option.
In the printing industry to provide high quality products, and technology is used adjust the color temperature at all stages of the production process.Optimal here is the value of 6500 K. At a given value of the light source generates in its structure, the ultraviolet component, is not perceived by the human eye.But some of the objects it is in this color temperature glow that gives printed products appeal and originality.Moreover, using technologies such effect is achieved in which the "whiteness" of the white paper is able to exceed a hundred percent value.
