if you are only using your camera in auto mode, you might as well be using a $100 point and shoot camera. You are only using 10% of this camera's full potential.
Now, first... I would suggest going to the library or local bookstore and get a book that explains basic concepts of shutter speed, aperture, and ISO, and how they all work together to control the exposure of the image, and the creative look and feel of the image..
Once you have a basic understanding of the elements of these concepts, you can switch out of AUTO mode....where the CAMERA dictates the shot, to moving into the other areas where YOU tell the camera what to do.
Now....to start with forget M mode for now. Thats Full Manual....And since you just read your book, and don't really have a clue as to how these things work yet, FULL manual is not for you

Its for someone with years of experience.
Also forget the P mode....that's called prgramed priority and is basically auto as well
So what does that leave for a true budding photographer to truely develop real skills?
The A and S modes.
These are called Aperture priority and Shutter priority.
Essentially, YOU control ONE of the two aspects and the camera suggests the other one. You then have full control through your
"exposure compensation dial" to correct the camera if you suspect the camera is telling you something other than your objective
Most people would tell you to start with the A mode. That's because the APERTURE aspect of the exposure determines what elements of the scene will be in clear focus and what will be blurred.
PHOTO tip 101: a small numbered aperture like 3.5means that what you focus on will be clear and the background will be blurry....a look that a lot of people like. A large numbered aperture like f16 means that everything will be in sharp focus.
If you were at a sporting even taking shots of fast moving action, you may wish to switch to the S mode, or shutter priority mode to give you direct control over the shutter speed fo freeze the action.
If you were using your favored AUTO mode in this instance, the camera might not know that you want to freeze the action!! IN S MODE, you TELL the camera to freeze the action. GET IT???
I'm sure this all sounds very confusing. So like I said, read up about all of these things so you get a better understanding...Then, read your manual because that tells you exactly how to use the A mode and the S mode and which dials control what.
PS...no self respecting photographer uses AUTO, any of the SCENE modes
with the fancy Icons, or the P mode.
They develop their skills using the
A mode or S mode, and then move on to the M mode once they have mastered the basics
