Austin Meyers first covers the use of Alpha channels, and working with premultiplied and unpremultipled images. He then moves on to demonstrate the most commonly used Merge operations and explains the math calculations which take place when they are used.

Finally, you will learn how to optimize your workflow by ensuring your Bounding Boxes are behaving correctly after merge operations.
