First off, not knowing your camera, or your proposed subject, I am going to assume that you are a beginner with a new camera.
Again, not knowing your camera, I suggest that you start by doing the following;
1-read the camera owners manual. Believe it or not, the manuals today are pretty good at getting you started and explaining not only what all the buttons do, but they will also let you know the limitations of the camera, both with explanations, but also with examples.
2-Again, I am assuming that your camera is digital. Knowing that, I suggest that you take a lot of pictures right away.
Take inside and outside pictures, along with pictures in low light and bright light.
Take pictures of fast moving things and slow ones.
Take close up pictures and some of thngs that are far away.
Once you have a decent collection of all of the variations of subjects, I mentioned above, sit down with your PC, and transfer the whole lot over.
Then take your time and observe each picture.
Try to remember what the conditions were when you took the pictures, and then take a critical look at them for overall quality.
You should have some good pictures, and some not so good.
This is when you get the manual out again, and see if you can figure out what went wrong with the bad ones.
This is the hard way to learn photography, but it is a good way to know the limits of your camera.
Now ...... If you have a top-end Nikon or Cannon, or whatever brand of camera, with a collection of lenses, flash units, etc. then go to the manufacturers web site.
They will (at least Nikon does) have abundant information on photography for the beginner as well as for the Pro.
They also have great tutorials.
The first lesson to learn, though, is to pull the camera out of it's case, and take lots of pictures, regularly.
Enjoy the good shots, and learn from the bad shots.
