Color correction by using Color Gel s, is a process used in Stage Lighting , Photography , Television , Cinematography and other disciplines, the intention of which is to alter the overall quality of the light measured on a scale known as Color Temperature . Every light source has a related color temperature that at its basic level describes how white the color of the light is. Color temperature is measured in Kelvin s (K), and the higher the value, the closer to the blue end of the spectrum the color is. For instance a standard household light bulb has a color temperature of about 3000 K, looking rather yellow. On the other hand a bright sunny day may give a reading of about 5600 K, appearing much bluer than the light bulb. Color correction therefore creates the possibility of making one light source appear to have the color temperature of another. This is very important in photography; for instance when a photographer wishes to capture an object on a sunny and bright day, but needs to add some artificial light to the subject to create the desired image. If a standard Tungsten - Halogen source was used it would appear very yellow compared to the rest of the available light. Placing a bluish gel over the light will color correct it, raising its color temperature to match the sun light. |
