Bleach Bypass

Apply the "bleach bypass" effect to the input image. This effect is well-known in movies like "300", it enforces shadows and desaturates the image. To ensure a good result, keep the slope value between 2 and 5. If your image is overexposed, you can increase the shadow offset. At the opposite, if your image is underexposed, you can decrease the shadow offset.

slopeFLOAT4.01–50The slope of the S-curve. keep value from 2 to 10 to expect good results.
shadow_offsetFLOAT0.500–1The shadow offset of the image. keep value near 0.5. If >0.5 the shadows are more present, <0.5 the lights are more present.
