Adjusting Threshold
The brightness of color and grayscale images is expressed in a value between 0 and 255. However, in
creating black and white images, all colors are mapped to either black (0) or white (255). "Threshold" is
the borderline value that determines a color as black or white.
Move
(Slider) to the right to increase the threshold value and thus increase the black areas. Move the
slider to the left to decrease the value and thus increase the white areas. You can also enter a value (0 to
255).
