Both contrasting shapes and those that complement one another can lend interest to a scene. Sometimes a small silhouette, because of its power to attract the eye, is all that is required to complete the puzzle. Now, if your photograph depends on the graphic strength of shapes or colors, try to simplify your composition so that they completely dominate the photograph. Focus in tight on the object, rather than including all the surroundings. Finally, ask yourself what shape would best fit your finished picture.
Many photographers prefer to make landscapes that really emphasize the horizontal.
To achieve this, they use wide angle and very wide angle lenses. That tends to give the photograph a three-dimensional feel. Most landscape photos are built so the eye is led from the foreground through the middle distance and into the far distance. When you take a landscape or scenic photograph, keep your eyes open for graphic elements that draw you into the scene and tie it together. If you do want to take a photograph that captures an entire scene, there is an alternative to spending a fortune on new lenses.
