Here is an untouched photo of some of the family at Disneyland this past June.
I did just a little cropping here to bring the photo more in harmony with the rule of thirds. You can see that there is less “sky space” and that the “bottom” part of the picture now takes up about 2/3 of the space. I also applied auto contrast.
This photo I edited in Picasa using Picnik. They have graph lines that make it very easy to compose your photo using the rules of thirds. Here you see that the cropped image puts Tori’s face at the top 1/3 intersection line (right side) which is where the human eye travels first. Also the flowers in the foreground add visual interest. I also adjusted the exposure to warm the colors in Tori’s face.
