A photograph is made of many things. Shapes, colors, patterns, and textures in an image can work in harmony to create a scene that really pops, or they can confuse the viewer with an uninteresting mishmash. Sometimes a color or texture can detract from an interesting shape or pattern. Exposing the scene to create a silhouette is a helpful trick here, especially when it creates some mystery!
