One of the principles of photography (and something that differentiates between a photograph and a snapshot) is that you place your point focus not in the center of the image, but at a position one-third of the way from either edge, or from the top or bottom. These photographs demonstrate this principle. If you are interested, here is a good post on the topic.
(Note: I took these images with a very cheap digital camera—a Vivitar F128. It cost around $12 and makes for a handy pocket camera for projects like this. But you can see some noticeable blurring around the edges of the images.)
Our eyes naturally go to the focal point in am image, in this case, the end of the road which is in the center of the image. There is a little visual interest because I was standing off to the side of the road, but nothing much is getting emphasized by this composition.
The focal point is in the bottom left corner of the image. This composition emphasizes both the sky and the stand of trees to the right.
The focal point is in the top left corner. This composition emphasizes the road.
The focal point is in the upper right hand corner. Had I been standing in the exact middle of the road, this image would have resembled the previous image to a large extent. But because I was at the edge of the road, this composition emphasizes the grassy area at the edge of the road.
The focal point is in the lower right hand corner now. Like the previous image, the grassy area to the left of the road is emphasized, but this is balanced out by bringing in a lot of blue sky.
