The pixels in the foreground and background zones are calculated independently from each other. Using a mask to define these areas can reduce the number of calculations. Simply move the cursor over the zones and assign a matte signal of 1.0.0 to these pixels. This way, the pixel in question will not be affected by the background. To create a seamless transition between foreground and backgrounds, you can use layers. Here are a few useful tips to help you make the most of them.
