I am using this online tutorial on masks to familiarise myself with this feature. In Final Cut Pro, masks allow you to block out an area for different treatment. I used a circle which I placed on the house in the picture. It is a technique which has a lot of potential however I am only just getting to grips with it. The third image has the ‘comic cool’ effect added. I like the way the shadows in the grass and cloud formations are exaggerated.
