Cavision 4x4" Glass Filter Set

The polarizer filter reduces light entering the lens that is oriented in a single plane (polarized light) without affecting color temperature. Light reflected off glass or water, as well as some of the light emitted from the sky on a clear day, is polarized. When rotated to the appropriate angle, the polarizer can largely eliminate reflections off glass or water. Furthermore, the polarizer will reduce glare and excess sky light, thereby increasing sharpness, contrast and color saturation of the image. Grad Orange 0.3 Glass Filter The graduated orange filter can be used to change the hue in one specific area of the image. One half of the filter is colored and the other half is transparent with a gradual transition between the two. The filter can be shifted and rotated in the filter stage to affect the portion of the image that is desired. All graduated filters are medium-soft edge Grad Blue 0.3 Glass Filter The graduated blue filter can be used to change the hue in one specific area of the image. One half of the filter is colored blue and the other half is transparent with a gradual transition between the two. The filter can be shifted and rotated in the filter stage to affect the portion of the image that is desired. The grad blue filter is especially useful for creating a blue sky effect. All graduated filters are medium-soft edge.
