Creating a Nozzle File of the Trees

Now that we have painted a number of different trees and placed them on different layers, we will combine them into a nozzle file that can be used with the Image Hose brush to paint a forest.

1. Select each Tree layer by clicking on it in the Layers palette while holding the Shift key; choose the Layer Adjuster tool in the toolbox and, with the Auto Select Layer box checked, drag over the layers you want to select in the document window, or click on the small menu arrow at the top right of the Layers palette and choose Select All Layers.

2. Group the selected layers using the Group Layers command in the Layers menu, or use the keyboard combination Ctrl+G (F+G on the Mac).

3. With the Tree layer group selected, go to the nozzle icon to display the Nozzle palette. Click the small menu arrow to the upper right of the Nozzle palette and select Make Nozzle From Group.

A new image is immediately created from the trees in the grouped layer. Each tree is placed on a grid whose size is determined by the largest tree in the group of layers. The new image has a black background, as you can see in Figure 4.8.

Figure 4.8 The new nozzle image created when the Make Nozzle From Group command is selected

Save the file in the native Painter RIF format; when naming the file, add the suffix nozzle to the image name. You should add this suffix so you can find the nozzle images easily among all your saved files. In this case, I named the new image tree nozzle.rif.

Return to the original image.

4. Hide the grouped Tree layer, but don't delete it. You'll use these trees later.

5. Pick the Brush tool and select the Tree Painter brush from the Book Brush library. Make the brush about 85 pixels in size.

6. Load the Tree Nozzle file. (This file is available for download.)

7. Create a new layer above the canvas, and paint a line of trees across the width of the background (Figure 4.9).

8. Name the layer Trees01 to avoid confusion with the multiple layers that you'll create.

9. Transform the layer slightly in the vertical dimension so the bottom of the trees is below the hill line. If needed, move the Tree layer down slightly using the Layer Adjuster tool.

10. Copy and paste the canvas into a layer above the Tree layer you just painted. You'll use this layer to adjust the value and colors of the trees behind them.

Row Painted Trees

Figure 4.9 A line of trees is painted across the width of the background.

For the remainder of this tutorial, each time the canvas is pasted above a Tree layer, we'll refer to it as the Tinting layer.

11. Lower the Opacity setting of this new Tinting layer to about 80%. The tree trunks now look much lighter and visually blend into the background (Figure 4.10).

It's possible to adjust the value and color of the background trees in several ways to accomplish the same effect, but I find that the method described allows a lot of flexibility should adjustments need to be made in the future.

Figure 4.10 The Canvas layer is copied and pasted, and the Opacity setting is reduced to cover the tree line.

A Second Row of Trees

Forests have depth, and we need to create additional rows of trees to give our image that illusion. To create the second row of trees

1. Create a new layer just above the first Tinting layer.

2. Pick the Brush tool, and once again select the Tree Painter brush. Make the brush size about 150 pixels.

3. Load the Tree Nozzle file.

4. Paint a second row of trees that follows the contour of the hill, and name the new layer Trees02 (Figure 4.11).

Figure 4.11 A second row of trees is painted on a new layer following the contour of the hill.

5. Select the Free Transform tool.

6. The icon for the Trees02 layer in the palette changes to indicate that the layer has changed to a Reference layer. An eight-handled box surrounds the new trees. It has four corner handles and four side handles.

7. Drag the bottom side handle down to lengthen the trees and hide their bases behind the Hill layer (Figure 4.12).

8. Right-click on the Trees02 layer and commit the transform. The Reference layer is changed back to a default layer.

9. Paste another copy of the canvas as a Tinting layer above the Trees02 layer (Figure 4.13).

10. Select the Trees02 layer and load a selection from the Select menu. When the Options box opens, select Tree02 Transparency and click OK (Figure 4.14). A marquee surrounds the transparent areas of the Trees02 layer.

Figure 4.12 The bases of the trees are hidden behind the hill using the Free Transform tool.

Figure 4.13 Another copy of the Tinting layer is pasted over the Trees02 layer.

Figure 4.14 The Load Selection dialog box with Trees02 Transparency selected

11. Invert the selection using the Select menu or use the key combination Ctrl+Shift+I (F+Shift+I on the Mac).

12. Click on the Tinting layer covering the Tree02 layer so it is active. The selection is still active and displaying the marching ants marquee.

13. Press the Backspace key. Most of the Tinting layer is deleted, leaving only those portions that cover the trees on the layer below.

14. Lower the Opacity setting of the active layer to about 60%. The trees are now about the same value and color as the hill they are on (Figure 4.15).

15. To reduce the number of layers, select both the Tree02 layer and the background layer above it and collapse the two using the Collapse command under the Layer Commands button at the bottom left of the Layers palette. You can also use the Collapse command in the Layers menu or the Crtl+Shift+X keys (F+Shift+X on the Mac).

Figure 4.15 The second layer of trees now appear to be about the same color and value as the hill they are on.

A Third Row of Trees

We'll go on to create the third row of trees in our painting. Each layer is created in essentially the same manner, with only slight variations.

1. Create a new layer behind the second hill and name it Trees03.

2. Size the Tree Painter brush to 200 pixels.

3. Load the Tree Nozzle file, and paint a third row of trees following the contour of the second hill (Figure 4.16).

4. Using the Free Transform tool, drag the bottom side handle down and lengthen the tree trunks to again hide their bases behind the Hill layer.

Figure 4.16 The third row of trees is painted using a larger brush and following the contour of the second hill shape.

Figure 4.16 The third row of trees is painted using a larger brush and following the contour of the second hill shape.

5. With the top side handle, scale the tops of the trees into the top quarter of the image (Figure 4.17).

6. Right-click the image and commit to a default layer.

7. Paste a new Tinting layer over the Trees03 layer.

8. Load a selection using the Trees03 transparency.

9. Invert the selection.

Figure 4.17 The tops and bottoms of the trees have been scaled using the Free Transform tool.

Select the Tinting layer and use the Backspace key to clear the layer except for the areas that cover the trees.

Lower the Opacity setting of the layer to around 34% (Figure 4.18).

You can determine the exact Opacity setting while looking at your own painting.

Collapse the Trees03 and Tinting layers together.

Figure 4.18 The colors are adjusted on the third layer of trees.

A Fourth Row of Trees

The remaining row of trees is painted using the same method. The only parts of the sequence that are different are the size of the brush used and the opacity of the background.

Create a new layer behind the Front Hill layer.

Using the Tree Painter brush and the Tree Nozzle sized to about 285 pixels, paint a row of trees running parallel to the Front Hill layer. Name the layer Trees04.

Use the Free Transform tool to scale the trees so the bottoms are below and behind the Front Hill layer and the treetops reach the top of the picture.

Commit the transform.

Paste another Tinting layer above Trees04.

Load a selection based on the transparency of the Trees04 layer.

Invert the selection.

Select the tinting layer and use the Backspace key to delete the tint except that portion that covers Trees04.

Lower the Opacity setting of the Tinting layer to about 10%. Collapse Trees04 and its Tinting layer.

There are now four rows of trees made from the original painted tree. Each row appears to fade into the distant background. The image should look something like Figure 4.19.

Figure 4.19 The four rows of trees are painted from one original tree. Foreground Trees

The final step for our forest is to add the foreground trees. We will not paint these trees with the Image Hose. Instead, we will use the trees we painted originally.

1. Select the top layer group. This layer group is hidden from view, but it should hold all the original trees, with each on its own layer.

2. Unhide the layer by clicking on the eye icon to the left side of the layer group.

3. Ungroup this layer group using the keys Ctrl+U (F+U on the Mac), or in the Layers menu select Ungroup.

4. Pick a few of the individual trees, and arrange their layers nicely in the foreground of the image using the Layers Adjuster. You will probably not want to use all the trees (Figure 4.20). You can delete those trees that you don't use.

The foreground trees may look very close in value and color to the second row of trees. To make these trees advance into the foreground and separate from the second row of trees, we need to darken their value and alter their color.

5. Select each front tree. In the Effects menu, choose Tonal Control > Adjust Colors. Darken the trees using the Value slider.

6. Warm the color of each tree using the Hue Shift slider.

7. Increase the color strength of the trees using the Saturation slider.

Figure 4.20 Individual Tree layers are arranged to make the closest part of the forest.

The level of change is up to you. I lowered the value about 30%, increased the z

Saturation about 11%, and moved the Hue Shift slider -15%. T

The front few trees are now distinctly darker and warmer than those behind EE

Figure 4.21 The colors in the front line of trees are adjusted to be darker and warmer.
