ptg 164 Chapter 7 If you want to sharpen or blur parts of an image, you can use the Sharpen, Blur, or Smudge tools. These tools are grouped together on the toolbox. The Sharpen tool (New!) increases contrast along edges to increase sharpness; the more you use the tool, the greater the sharpening effect. The Blur tool softens hard edges or reduces detail; the more you use the tool, the greater the blur effect. The Smudge tool creates a finger drag through wet paint effect.

The Clone Source panel contains five clone buttons to which you can assign samples. Simply open the Clone Source panel, click a Clone Stamp but- ton, and then select the sample you want. The Clone Source panel saves the samples until you close the document. To help you clone the source in a specific location, you can overlay your sample source and show the overlay on the screen. The overlay allows you to view your changes and helps you visualize where to paint. In addition, you can scale and rotate the sample source to clone the sample at a specific size and orientation as well as use the Flip buttons for reversing the clone source (New!). If you need to paint in a very specific location relative to the sampling point, you can use the x and y pixel offset. Setting Up Multiple Clone Sources Use the Clone Source Panel Open a document. Click the Clone Source button to display the Clone Source panel. To de termine if a Clone Stamp button is in use, point to it to display a Screen Tip. Click a Clone Stamp not in use, or one you want to replace. To se t a sample point, Alt (Win) or Option (Mac), and click a point. To sh ow the overlay, se le ct the Show Overlay check box.

Select a brush tip, and then select brush options, such as blending mode, opacity, and flow, on the Options bar. Select the Aligned check box on the Options bar to sample pixels continuously without losing the current sampling point. Clear the check box to continue using pixels from the initial sampling point each time you stop and resume painting. Click the Sample list arrow on the Options bar, and then select the layer option you want to use to obtain sample data: Current Layer, Current & Below, or All Layers. Hold down the Alt (Win) or Option (Mac) key, and then click an area to sample the portion of the image you want to use for your sample. Drag over the area of the image you want to restore or modify. To se lect more samples, click the Window menu, click Clone Source, click a clone button, and then repeat steps 5 & 6. 7 6 5 4 3 2 1 One of Photoshop's most powerful features is its ability to retouch a photographic image. When you want to manipulate an image, you can apply the Clone Stamp tool. The Clone Stamp tool allows you to sample the image, and then apply that sample somewhere else on the same image, or on another open document. When you use the Clone Stamp tool, by selecting Aligned in the Options bar, you can reuse the most current sampling point no matter how many times you start and stop painting. When Aligned is deselected, you'll reuse the same sampled pixels each time you paint. For example, you could use the Clone Stamp tool to repair damage to an image, remove a tree, or even remove or add someone from an image. If you want to take multiple samples, the Clone Source panel allows you to set up to five different sample sources for the Clone Stamp or the Healing Brush tools. Select Show Overlay and the Clipped option to see the clone source inside your brush cursor as you paint. 1 Joshua tree removed using the Clone Stamp tool. 7 From the Library of Wow! eBook ptg Chapter 7 Working with Adjustment Layers, Filters, and Tools 167 You can also use the Dodge and Burn tools to lighten or darken specific areas of an image. If you wanted to lighten the shadow areas of an image, you would use the Dodge tool, and conversely, if you wanted to darken the highlight areas of an image, you would select the Burn tool. While there are other ways to control the highlights and shadows of an image, such as a Levels adjustment, the Dodge and Burn tools are con- trolled by using a brush and painting in the image. That kind of control gives you the option to choose exactly what you want to modify. Using the Dodge and Burn Tools Use the Dodge and Burn Tools Select the Dodge or Burn tool on the toolbox. Select a brush tip, and then select brush options on the Options bar. Click the Range list arrow on the Options bar, and then click Midtones (middle range of grays), Shadows (dark areas), or Highlights (light areas). Specify the Exposure value for the stroke. To us e the brush as an airbrush, click the Airbrush button. Alternately, select the Airbrush option in the Brushes panel. Select the Protect Tones check box to minimize clipping and reduce hue shifting within the image. Drag over the part of the image you want to lighten or darken. 7 6 5 4 3 2 1 2 3 4 5 1 Dark areas restored using the Burn tool Did You Know? The Sponge tool does not lighten or darken an image. It saturates or desat- urates color values as you drag over parts of the image. Since overexposed or underexposed images have a ten- dency to lose some tonal values and appear flat, you can use the Sponge tool (with Saturate) to return some of the color values back to the image. 6 From the Library of Wow! eBook ptg 168 Chapter 7 Using the Healing Brush and Patch Tools Use the Healing Brush Tool Select the Healing Brush tool. Select a soft round brush on the Options bar. Create a new layer above the layer you want to modify. Click the Sample list arrow, and then select the layer option you want to use to obtain sample data: Current Layer, Current & Below, or All Layers. Hold the Alt (Win) or Option (Mac) key, and then click on the area of the image for a sample. This area should represent the texture (not color) of the areas you want to heal. Use small short strokes and carefully drag over the areas you want to change, then release your mouse and move to the next area. The Healing brush works to match the sample to the source. If the texture of the area you are healing changes, repeat step 4, and sample a different area. 7 6 5 4 3 2 1 These tools have become my favorite tools for working with digital images and correcting problems. The Healing Brush tool allows you to correct small imperfections, making them disappear into the surround- ing image. This tool works from a sample of the original image, and then matches the texture, lighting, transparency, and shading of the sampled pixels into the source pixels. If an image contains a lot of random noise, before working with the Healing Brush, try lowering the amount of noise with the Reduce Noise filter. After you've applied the Reduce Noise fil- ter, you can use the Healing Brush to clean up the rest of the problem areas. The Patch tool takes a sample and matches the texture, lighting, transparency, and shading of the sample to the source, creating an almost seamless repair of the image. You can also use the Patch tool to clone isolated areas of an image. When you use healing operations in a separate layer, you gain control over the process; you can even use the opacity and blending mode settings to further control the healing process. Always use the Healing Brush in a separate layer…always. 1 2 4 The image contains scratches and spots The Healing Brush makes short work of correcting damaged images. From the Library of Wow! eBook ptg Chapter 7 Working with Adjustment Layers, Filters, and Tools 169 Use the Patch Tool Select the Patch tool. Select the layer you want to modify. Using the Patch tool, select the damaged area of the image you want to repair (the Patch tool functions just like the Lasso selection tool). Click the Source option on the Options bar. Move into the middle of the selection marquee, and drag the selection over the area you want to repair and release. As you drag, you will see a copy of the area you are moving over appear in the original selection. Release your mouse when you see the best match. The Patch tool corrects the damaged area of the image. Repeat steps 2 through 6 to patch any other damaged areas of the image. 7 6 5 4 3 2 1 3 4 The Patch tool removed the rings under the model’s eyes. Did You Know? The Patch tool options on the Options bar provide power. On the Options bar, use the Source option with the Patch tool if you are selecting the damaged area and dragging it over the good area, and use the Destination option if you would rather select a good area to drag over the damaged area. The Transparent option preserves transpar- ent areas during the patching process. 1 From the Library of Wow! eBook . ptg 164 Chapter 7 If you want to sharpen or blur parts of an image, you can use the Sharpen, Blur, or Smudge tools.
