Layers and patterns are similar, but layers have a slightly different element: dimension. While layers can also be repeating, they show depth and shadows as well. In my landscape photography, I often look for lines to help create dimension as layers are stacked one on top of the other (Figure 4.17).
Figure 4.17 Notice how the layers are outlined by lines stacked on one another.
