Create a new Object in this case I have created a sphere primtive.
(1) Select the Camera
(2) In the objects attributes panel open up the animation palette.
(3) Notice the camera is not tracking anything.
Step 2
(1 & 2) In the drop down tracking menu, signified the target symbol, in the atributtes palette, select the object you want to track (make the camera alway point at it.)
If you dont want the camera to track anything just select no track from the drop down menu.
Now if we move the camere are the sphere or the camera will always point at the sphere.
