Schneider Optics. Coral (Warming) Filters are considered to be both color-correction and color-effects filters, Schneider Optics 6.6" x 6.6" Coral filters are used to warm cool lighting situations such as overcast days and scenes in open shade. Different strengths of Schneider Coral filters can be used during filming to achieve the same degree of apparent warmth under different light conditions. This makes them particularly useful for maintaining a consistent color balance throughout an entire day of shooting, or to create a sunset or dawn effect during the day. Schneider Coral filters can be used to under-correct a scene in order to create an excessively blue look for added drama, and can also be used as warming filters to create other dramatic effects.
Schneider Coral filters may be used alone or in combination with other color correction filters.
Schneider Coral filters can be combined with the Schneider 85 filter to create exciting results. For example, Directors of Photography will often spice up a scene by combining an 85 with a Coral #2, to create additional warming.
Cinematographers who own a complete set of Schneider Coral filters have the ability to control just about any outdoor lighting situation. Because all Schneider filters are designed and manufactured with the highest possible degree of consistency, you can swap same-number Coral filters in mid-shoot without a discernible variation in color or effect. This unprecedented level of consistency enables Directors of Photography to shoot with multiple cameras and replace lost or damaged filters during production with absolutely no visible change in the warming effect.
Schneider Coral filters are made from crystal-clear water-white optical glass, and are protected against edge-chipping and delamination by Schneiderﾒs unique Edge Seal, which also reduces edge-reflections and flare.
Schneider Coral filters are available in densities of 1/8, 1/4, 1/2, 1, and 2.
