I would like to learn about...........

I had poor ability to use the computer before I took the computer class. And I learned many things in this class. However, I want to learn more about the computer. For example, editing the pictures, music, and movies. I often take the photo or video in the activity of my tennis club. And also, I show them to my teammate. But I don't want to merely show pictures or movies. I want to make much more funny pictures or movies to amuse my teammate.
