Hand-coloring selections on a layer


You'll start to add special effects to your montage by hand-coloring the pears, beginning with the pear on the right. To select it, you'll simply load the first selection you created in the previous procedure. Then, you'll remove the color from the selection so that you can color it by hand. Finally, after adding a layer above the pears, you'll be ready to apply new color by adding it to the new layer. In this way, you can simply erase the layer and start over if you don't like the results.

Desaturating a selection


You'll use the Desaturate command to remove the color from the selected pear area. Saturation is the presence or absence of color in a selection. When you desaturate a selection within an image, you create a grayscale-like effect without affecting the colors in other parts of the image.


1.

In the Layers palette, select Layer 1, the layer with the pears image.

2.

Choose Select > Load Selection.

3.

In the Load Selection dialog box, choose Right Pear from the Channel pop-up menu, and click OK. A selection border appears around the right pear in your image.

4.

Choose Image > Adjustments > Desaturate. The color is removed from the selection.

5.

Choose Select > Deselect.

6.

Choose File > Save to save your work. If you get a compatibility warning, click OK.


Creating a layer and choosing a blending mode


Now, you'll add a layer and specify a layer blending mode for painting the desaturated pear image. By painting on a separate layer, you won't permanently alter the image. This makes it easy to start over if you aren't satisfied with the results.

Layer blending modes determine how the pixels in a layer blend with underlying pixels on other layers. By applying modes to individual layers, you can create a variety of special effects.


1.

In the Layers palette, click the Create a New Layer button () to add Layer 5 to the image, just above Layer 1 in the palette.

2.

Double-click Layer 5, type Paint to rename the layer, and press Enter (Windows) or Return (Mac OS).

3.

In the Layers palette, choose Color from the Blending Mode pop-up menu to the left of the Opacity text box.

NoteIf you ever want to delete a layer, you can drag it to the Trash button at the bottom of the Layers palette. Or, simply select the layer you want to delete and then click the Trash button and, when prompted, confirm that you want to delete the layer.

You can use the Color mode to change the hue of a selection without affecting the highlights and shadows. This means that you can apply a variety of color tints without changing the original highlights and shadows of the pears.


Applying painting effects


To begin painting, you must again load the selection that you created earlier. By loading the Right Pear channel, you protect the unselected areas of the image as you apply colors, making it easy to paint within the lines.


1.

Choose Select > Load Selection. In the Load Selection dialog box, choose Channel > Right Pear, and click OK.

Notice in the Load Selection dialog box that the color-mode change you just made also was saved as a selection, called Paint Transparency.

2.

Select the Brush tool (). Then, on the tool options bar, type, scrub, or drag the slider to set the Opacity to about 50%.

Change the brush opacity by pressing a number on the keypad from 0 to 9 (where 1 is 10%, 9 is 90%, and 0 is 100%).

3.

In the Brush pop-up palette, select a large soft-edged brush, such as the Soft Round 35-pixel brush. Click off the palette to close it.

4.

Choose Window > Swatches to bring the Swatches palette forward (or click its tab in the Color palette group), and then select any yellow-green color that appeals to you as your foreground color.

5.

Drag the brush over the entire pear to apply the color.

Next, you'll use a darker and a lighter shade to add highlights and shadows.

6.

Select a darker green from the Swatches palette. On the tool options bar, set the brush opacity to about 30%. Paint around the edges in the pear selection, avoiding the highlight area.

7.

Select a rose color from the Swatches palette. On the tool options bar, select a smaller brush size and decrease the opacity to about 20%. Then, paint highlights on the pear.

8.

When you are satisfied with your results, choose Select > Deselect, and then choose File > Save.


Adding a gradient


Now you'll use the Gradient tool to add a gradient to the other pear for a highlight effect. First, you'll need to load the selection of the left pear that you made earlier.


1.

Choose Select > Load Selection. Choose Channel > Left Pear in the Load Selection dialog box, and click OK. A selection border appears around the left pear in your image.

2.

Lesson 16, "Producing and Printing Consistent Color," and Photoshop Help.

4.

Select the Gradient tool (). On the tool options bar, do the following:

Select the Radial Gradient button.

Open the gradient picker and make sure that Foreground to Background is selected, so the color blends from the foreground color (red) to the background color (yellow).

Set the Opacity to 40%.


A. Linear gradien

B. Radial gradien

C. Angle gradient

D. Reflected gradien

E. Diamond gradient

Selecting Foreground to Background

5.

Position the Gradient tool near the pear's highlight, and drag toward the stem end.

6.

When you're satisfied with the results, choose Select > Deselect.


Merging layers


The next task, merging layers, helps you to keep the file size relatively small. However, after you merge, you cannot easily go back and restore the image or start the process over, so be sure that you are happy with your results before you choose a merge command.


1.

In the Layers palette, make sure that the Paint layer is selected.

2.

Choose Layer > Merge Down to merge the Paint layer with the pear-image layer (Layer 1) below it.

Now the two layers are fused as Layer 1.

3.

Double-click the Hand tool () so that the entire image fits in the image window, or double-click the Zoom tool () to set the view to 100%.

4.

Choose File > Save.
