The b channel contains blue and yellow color information. Moving the slider all the way to the left (-1) shifts the blue and yellow colors to blue; moving the slider all the way to the right (1) shifts the blue and yellow colors to yellow. |

Select the checkbox to invert all luminance values, which creates a negative image. |
