Variable ND Filter Optical Glass Viewing Filter HD Filters For Viewing Light
The color resolution of human vision is inconsistent with that of photographic plates. The human eye often lacks resolution for some colors under strong light source. Without the help of a light-viewing filter, it is difficult to anticipate the color reflected from the photographic film. Some even lose the original color, so that the tone of the bright part and the dark part can not be guaranteed. With the help of the viewing filter, we can observe the color density and contrast of the object under the illumination of different light sources. By adjusting the light and assisting the use of light legal person, we can calibrate the color of the scene in the later stage of the film, so that the color, brightness and level of the scene can be correctly reflected from the photographic film.
