The Brightness and Contrast effect allows you to modify the brilliance or dullness of an image or to create a greater difference between the lights and darks of an image by increasing their respective intensities. This effect can be used when an image appears too flat. Increasing the brightness or contrast can give a drawing a more attractive and 3D quality. This can be useful if you want to push your background to the rear by making it look dull and flat and pulling your foreground elements to the front by giving them a higher contrast.
Connection
The Brightness-Contrast effect layer must be connected as a child of the drawing layer or group which you want it to affect.
