ABSTRACT
Travel mattes, or traveling mattes, are a unique type of composite mode that uses the underlying layer in a composite stack to define an image’s transparency. It allows the application to create a great many wonderful motion graphics animations. The pale text file’s transparency is being directly controlled by the luminance value of the layer beneath it. The matte layer, the Highlight in this case, is invisible. An alpha matte uses the transparency of the layer, like text layers, to create transparency in the layer to which the composite mode is applied. At the moment, the glint brushes across the upper-left edge of the letters as it moves back and forth across the screen. Color mattes can also be used as a color filter. Day for Night is the now seldom-used technique of trying to shoot in daylight and make it look like a moonlit night. Old Westerns almost always used this technique.
