PCT No. PCT/NL80/00033 Sec. 371 Date Jun. 19, 1981 Sec. 102(e) Date Jun. 19, 1981 PCT Filed Oct. 15, 1980 PCT Pub. No. WO81/01203 PCT Pub. Date Apr. 30, 1981.A color analyser measuring the light intensities of at least three different colors within the spectrum of the incident light, and relating these measurements to values programmmed before. Those color components of the incident light that have to be influenced in order to conform to the preprogrammed relations are indicated by means of a color star, consisting of three rows of light sources (23, 24, 25) of appropriate colors. While influencing the color of the light with correction filters the operator views the change simultaneously at the color star. It is indicated in such a way that the light sources of the color star are extinguished as soon as the preprogrammed relations between the colors are satisfied, notwithstanding the absolute value of light intensity. An automatic exposure time meter is built in, also controlling an electronic timer (32).
