When you are new to photography, you probably use your camera in auto mode. And that is a great place to start, especially since modern cameras are remarkably competent at creating balanced images. Nonetheless, if you want to advance your photography, you will need to eventually embrace semi-automatic and manual modes, and this great video tutorial will show you six ways to start taking more control of your camera and your photos.
Coming to you from Photography Pro, this awesome video tutorial will show you six different ways to get your camera out of auto mode and take more control of your photography. One important thing to remember is that while manual mode offers you the most control, it is not actually always the best choice. In fact, a lot of top-level professionals use semi-automatic modes all the time. For example, a lot of wedding photographers use aperture priority mode to keep control over the depth of field while allowing the camera to handle creating a balanced exposure, since they may be moving through very quickly changing lighting scenarios and not have the time to devote to completely controlling the camera while also handling everything that goes into wedding work. Check out the video above for the full rundown.

I personally prefer the Program mode on my Pentax cameras. Since they have two wheels I can adjust both aperture and shutter on the fly. It gives me a lot of control and flexibility.
That is just me, whatever floats your boat.
