The first aspect of composition is symmetry. Symmetrical composition is a balanced scene, "the horizontal line splits the scene exactly in half" (87). Asymmetrical composition is the opposite of symmetrical composition. This type of arrangement is more appealing and realistic.
The last aspect of composition is cropping. Cropping and formatting is taking out unneeded visual information and including only the most important part of the scene. Willenbrink suggests to use a viewfinder, it is type of method where you use "a piece of cardboard with a cutout like a window frame" (89). This is most helpful when working outdoors, "when the subject may seem overwhelming and you dont know where to focus your attention" (88). Another method to form a scene is forming a rectangle with your fingers, for this you dont need any equipment.
