Step 4
For the areas that need deeper shadows, first start by filling the area on a separate layer as usual with a solid color, perhaps taken using the Eyedropper tool from nearby areas. Then, add some noise to this layer, at a very low setting such as 1 (Filter>Noise>Add Noise). This adds to the realism and makes it less sterile looking. Then using the Clone Stamp tool, Alt-click (MAC: Option-click) in a nearby source area and then release and click-and-drag in the new area to create the correct look. Use the same technique as earlier to create shadows on some of the edges (use a large, soft brush on the edges of the selection).
