Now that we have some experience in creating mask shapes let's put what we know to work,…masking a different piece of footage and editing that mask shape.…Again, if you have the Exercise Files in this lesson, open up…comp 01-Masking*starter.…If you don't have the Exercise Files, I just have two pieces of footage in this composition.…One is the foreground, it has some interesting objects that I want to mask out,…And the other is an interesting background that I want to reveal behind this…layer I'm about to mask.…Turn the visibility back on.…Make sure my target layer is selected, so that I am masking the correct layer…and not creating a shape layer.…
And I am going to pick the Rounded Rectangle tool.…I want to start by isolating some of these buildings.…So what I'm going to do is going to click and start dragging until I can see the…buildings and a bit of this freeway.…It's kind of a nice arrangement.…If I am not happy I can add Spacebar before I release the mouse and reposition…my mask, but I'm going to put it right around there.…
