I found a great image while looking on flickr.com. It is of a Bernese Mountain Dog who is laying down on some grass. Upon initially viewing this image I thought the photographer had employed Rule of Thirds, but the longer I looked at it the more I felt that was wrong. So, to double-check I decided to apply a rule of thirds grid and a diagonal grid to see which aligned better. After testing the two out I realized that this image makes more sense as having used the diagonal method. The photographer used a shutter speed of 1/250. I believe this shutter speed may have allowed for just the right amount of light and shadows. Any faster and it would have made the image too bright and slower would be too dark. The blurred background is a clear sign of a lower depth of field, he specifically used f/5.6 to get this look. It really helped make this image better for me. It draws the focus to the dog while also making him seem sharper.
