Bleach Bypass simulates the harsh, high contrast look of bleach bypass film processing. Often used for war movies. Bleach bypass takes its name from a technique used to develop color film stock. By skipping the bleaching step in the development process, the silver in the film emulsion is retained, resulting in a black-and-white image laid over the color image. The final image has reduced saturation, and increased contrast and graininess.
- Amount: The intensity of the Bleach Bypass effect applied to your source video.
- Brightness: Adjusts the brightness of the video. Actual film is typically shot 1 stop underexposed to prepare for bleach bypass processing, to compensate for the brightening that occurs during the process. This slider allows you to compensate for the brightness of your source video to get the result you want.
- Silver Source: You can change the source used to create the Silver map used by the bleach bypass here. Choose the Intensity of the image, the Luminosity of the image, or the Lightness of the image. This is a case where its best to just try the options, and see which one gives the most pleasing result.
