When other compositional ideas are not working, find a way to direct the eye by including a path in your photograph.
Here is a shot I took on a neighborhood trail. A clear path takes the viewer up through the image and through the natural tunnel. O f course, you will not always have such a clear path to incorporate in your photograph.
Sometimes, you have to really hun for these paths. In the case of this next picture I took on the Oregon coast, I found the water path first and then moved around to direct it somewhere interesting in my image.
Here is a similar example I took on a snowy day. In on otherwise colorless and white-washed photo-shoot, I found a few of these breaks in the snow that created compositional tools in my pictures.
When you are struggling to come up with a pleasant composition, try making a path in your picture. Lead the eye to just about anything and your pictures will come alive. I believe a great photograph can make the mundane, magnificent.
