USING PLUS GREEN CINEFILTERS
Plus Green CineFilters are designed to be added to sources being used as fill lights where there is a predominance of fluorescent lights that cannot be eliminated. Fluorescent light sources have a very high green peak and therefore it is often necessary to correct the film or to adjust the video system to eliminate the green. Since fluorescent fixtures are usually mounted to the ceiling filling large areas such as a supermarket with light, it's hard to avoid them. Turning them off would leave great masses of black holes.
Plus green filters will reduce the red and blue output of the light source, thus creating a green spike simulating the fluorescent lamp. By adding plus green filters to incandescent and HMI lights used to augment the predominately fluorescent lighting they can simulate the fluorescent light. The resulting photography is then corrected in the lab where the "green" is eliminated. This approach is not the best solution for color quality but offers a fast fix to shooting color under fluorescent lamps.
Plus Green GamColor CineFilters can also be used in front of HMI lights that are being used as fill lights where mercury vapor or fluorescent lights are in use.
Large windows which have ultraviolet filters imbedded in them often have a distinct pink shift. When this happens you can use the 8 Plus Green filters on the windows or in fill lights to help balance this pink shift.
Another interesting application of Plus Green filters is to make plants in the background of a shoot look a little richer. Plants in the background of a shot very often look dark and dismal. By using 1/8 or 1/4 Plus Green GamColor CineFilters you can bring out the green color of the plant life.
