Practicing Camera angles

To practice using cameras along a constrained path, I am going to use the text I have created for the steam engine title. I would like to be able to look with the camera at the title going around in an arc shape.

Firstly i created an arc, in Splines. I chose this just for example, I could have chosen any shape to work with.

I selected a camera, and used target as the property.I put the camera in the middle facing the text.

Making sure the camera is still selected. I clicked on animation from the tool bar at the top then constraints , then path constraints, I then clicked on the path which is the arc and it automatically assigns itself to it, following the path with the camera.

Now that the constraints path has been set, you can click on the camera and it can move along the path smoothly. So all that needs to be done is animation now.
