The Rule of Thirds simply put is to divide up your image into 9 equal squares as seen here. The four intersecting points (called "power points" by some) can be used to align objects in your pictures. It has been around for quite a while and the first published incidence was in 1845 as a rule for scenic paintings. Some people feel that following the Rule of Thirds gives more energy and movement to a picture and makes it more aesthetically pleasing.Your points of focus in a picture don't necessarily need to be at the exact intersection points as getting subjects to line up perfectly while shooting on the fly isn't always a possibility. Let's look at some of my own shots to see how they shape up using the Rule of Thirds.

First we'll look at a candid shot of my Brother-in-law, Grant and my in-laws dog, Riley. This was just a quick shot taken while we were taking a break putting drywall up on the garage ceiling at my in-laws.
After taking the picture I had noticed it would have looked better if Riley had been a bit more in frame and we can see why when looking at the overlay. He's just a little to far left of the intersection point. Grant's face is ok where it is as it is resting against the "power point." Grant's hand is almost perfectly located at the lower right intersection.
All in all it's not a bad shot and carries some emotion in the look in both Grant's and Riley's faces. That's a whole other composition topic however and I won't get into a pictures "meaning" here.
So you can see how the Rule of Thirds applies in the composition of a picture and how it can make it more visually pleasing.
Next we'll move onto this shot of my cat, Bo. Yes, this shot again. I feel the Rule of Thirds is working well in this picture. The top intersecting points catch the ears and the bottom two are close enough to the eyes.Another thing to remember is the empty space in a picture. In this picture the top third and two third of the upper right are essentially empty which draws the eyes completely to the subject. Which is of course what one wants in portraits.
This is one of my better shots taken with the K10D and this one is an unedited version. I didn't even know what the Rule of Thirds was when I took this shot but I knew it was pleasing to look at once I saw the picture on the LCD of the camera.
I try to pay attention to how objects are lining up in my viewfinder and do attempt to follow the Rule of Thirds for most shots. For some SLR and dSLR cameras you can get different overlays for your viewfinder that actually have the Rule of Thirds overlay. The one in my K10D gives a rough estimate and works ok. If you are using a point and shoot camera then you may just have to rely on what you see in the viewfinder (you don't use just your screen to shoot right?).
That's just an extremely limited and beginning intro to the Rule of Thirds. I know there is more to add but this is just a blog;-)
