Enhancing the Scene with Shadows

Adding some shadows on the tree trunks is easy, and the shadows will dramatically enhance the appearance of the scene. We'll add shadows for both the first and second rows of tree trunks on their own layer. The Trees layers that are deeper in the background will not benefit from adding shadows.

To add shadows to the first row of tree trunks

1. Create a new layer on top of the first row of tree trunks.

2. Change the Composite Method of the new layer to either Gel or Multiply. Either works equally well.

3. Load a selection based on the transparency of the first layer of tree trunks.

4. With the selection still active, move back to the new Multiply layer.

5. Use the Leaf Painter brush, a mid-value gray as the secondary color, and the Grain amount set to 0 in the Brush Options menu at the top of the screen. Then paint some shadows on the tree trunks (Figure 4.29).

Because a selection is loaded based on the Tree Trunk layer's transparency, the shadows are painted only on the trunks and not into any of the background.

If the selection marquee is distracting, it's possible to hide it in the Select menu by choosing Hide Marquee.

6. After you paint the leaves, select the Digital airbrush or another airbrush of your choice. Paint the shadow sides of the tree trunks on the same layer as the leaves shadows using the same gray color (Figure 4.30).

7. Deselect the layer using either the Select menu or the keyboard combination Ctrl+D (F+D on the Mac). This is particularly important if you hid the marquee in an earlier step.

Sometimes if the marquee is hidden, it is easy to forget that there is a still a selection. More than one artist has become extremely frustrated trying to paint in an image and not being able to make a mark because a hidden selection is active.

We'll add shadows to the second row of trees using the same technique as before.

1. Create a new layer above the second row of trees and set it to either Multiply or Gel.

2. Load a selection from the second row of trees transparency.

3. Add shadows on the trunks using the same brushes used earlier (Figure 4.31).

Figure 4.31 Shadows are added to the trunks of the second row of trees.

Slightly blur each Shadow layer using Effects > Focus > Soften. The default setting of 3.0 is fine.

To finish the shadows, collapse each Shadow layer with its respective Tree Trunk layer.
