The BCC Halftone ﬁlter recreates the look of printed material by converting the image to simulated halftone dots.
Print images are comprised of a rosette pattern of colored ink dots. To avoid moire or interference patterns, the dots are printed at different angles; this process is known as halftone screening. This is also used in the art world as a creative process such as the work produced by Lichtenstein.
In addition to control over the individual halftone dots, the filter offers comprehensive control over the color of the paper on with the image is "printed."
- When Automatic is chosen, the paper color is set to black when the Color Scheme menu is set to RGB and white for other Color Scheme menu settings. The Paper Color parameter is ignored when Transparent is chosen.
- When Color is chosen, the Paper Color parameter in the Colors & Angles parameter group sets the color of the paper.
- When Transparent is chosen, the paper generates an alpha channel. This allows you to composite the Halftone effect over tracks lower in the timeline. The Paper Color parameter is ignored when Transparent is chosen.
- When Original Image is chosen, the paper is composited over the ﬁltered image. The Paper Color parameter is ignored when Transparent is chosen.
The built in PixelChooser, with integrated mocha planar tracking allows for greater control over which areas of the image the ﬁlter should affect.
