CIFilter.CompositeOperation.HardLightBlendMode

Discussion If the source image sample color is lighter than 50% gray, the background is lightened, similar to screening. If the source image sample color is darker than 50% gray, the background is darkened, similar to multiplying. If the source image sample color is equal to 50% gray, the source image is not changed. Image samples that are equal to pure black or pure white result in pure black or white. The overall effect is similar to what you would achieve by shining a harsh spotlight on the source image. The formula used to create this filter is described in the PDF specification, which is available online from the Adobe Developer Center. See PDF Reference and Adobe Extensions to the PDF Specification.
