Sažetak
The light in a photographic process is of major importance for the overall quality of reproduced scene. In practice, a photograph is made in different lighting conditions and out of different light sources. Light sources emit the radiating energy of continuous spectrum which is being perceived to a human eye as white light. The emission of this radiation, its density, is defined as the temperature of the color of light. This paper will demonstrate influence of different color temperature (light sources) on the quality of digital photography with automatic white balance (AWB) at constant remaining parameters. Color gamut was defined by using colorimetric analysis of test chart photograph shooting in three different lighting conditions. On the basis of CIELAB value for three different conditions and standard value, color differences (ΔE) were calculated for primary (RGB) and secondary (CMY) colors additive synthesis.
