Simulates the bleach bypass technique, involving the partial or complete skipping of the bleaching function during the processing of a color film. The result is a black and white image over a color image. The images usually would have reduced saturation and exposure, along with increased contrast and graininess.
Effect Parameters
Amount
This parameter controls the intensity of the effect. A value of 1 means that the output image is based entirely on the output of the “Bleach Bypass” simulation. A value of 0 displays the original media, unmodified.
High-precision Output
This parameter, available only inside Final Cut Pro, controls the color range of the final output. Although you will see no difference in the Canvas window (due to the fact that Final Cut Pro always previews in 8 bit color) high-precision clamping ensures that your output falls within a predictable range. This feature will often save you an extra post-processing step and come in handy when the only previewing device available is the built-in display.
