Correcting and Retouching

After you’ve corrected the light and color of your photo in general, it’s time to move on to the on-the-spot corrections You can remove flaws or red-eye in your photo, use the adjustment brush to make color or lighting corrections to selected areas of your photo, or create a graduated filter to apply a color or lighting effect gradually Although all these changes have the potential to bruise your image or create noise, they are considered non-destructive edits because you can always return to the original camera raw settings

Spot removal and cloning

The Spot Removal tool allows you to make localized spot correction and cloning fixes to anything from lens spots to blemishes Here in Camera Raw, the tool is limited compared to the tools you find in Photoshop for cloning and healing For the basic fixes, however, it works just fine, limiting the reasons to even take the time to open your image in Photoshop

Tip

If you have a lens or sensor spot that appears in multiple photos and can be fixed adequately in Camera Raw,

be sure and take advantage of the fact that you can fix multiple photos at once You can open them all at once

in Camera Raw or use the batch editing capabilities of Bridge, which you can read about in Chapter 6 n

To use the Spot Removal tool, follow these steps:

On the Web Site

You can download Figure 8-24 from the Web site and follow the steps to learn how to use the Spot Removal

tool n

1 Open the file Figure 8.24, as shown in Figure 8.25

2 Click the Spot Removal tool

This changes your cursor to a crosshair and activates it and opens the Spot Removal

panel, also shown in Figure 8.25

3 Select Heal from the Type drop-down menu.

The Heal option takes the texture, lighting, and shading from the sampled areas and places it over the blemish The Clone brush simply makes a copy of the sampled area and places it over the blemish, feathering the edges so they blend in

4 Select the blemish.

Drag to create a circle that is just larger than the mole, and let go of the mouse button A red circle indicating the area to correct is created over the blemish, and a second, green, circle is also created, indicating the area that is being used to create the patch

FIGURE 8.25

Is this a beauty mark or a blemish? Either way, the Spot Removal tool gets rid of it

5 Move either circle, if needed.

Camera Raw makes a guess at which area is the best to take a patch from when it places the green circle This guess is frequently wrong Move either circle by hovering over the center of it until the arrow and plus sign appear, as shown in Figure 8.26, and then grab-bing and moving it to a better location

6 Resize the circles, if needed.

You also can resize both circles by using the radius slider or by hovering over the edge of either circle until the two-directional arrow appears and then dragging them to the right size

7 Deselect the Show Overlay option to remove the circles from view and make sure

everything looks good.

8 Make as many more healing or cloning changes as you need to.

As you click to create new circles, the old red circles turn purple, indicating that they are not active, and the old green circles disappear

9 Select any other tool to exit the Spot Removal panel.

FIGURE 8.26

Wait until you see the arrow and plus sign before you move one of the circles

Note

To start over, click Clear All to remove all sampled and fixed areas n

You can use the Opacity slider to reduce the effect of the spot removal You can do this before or after you have created the healing circles The Opacity (as well as the Radius) works only on the active circles

Red-eye removal

You can make quick red-eye fixes in Camera Raw from the Red Eye Removal panel that is accessed

by clicking the Red Eye Removal tool Use the tool to drag a marquee around each red eye, making the marquee a little larger than the eye itself, as shown in Figure 8.27 Deselect the Overlay so you can see how well your fix worked Use the Pupil Size and Darken sliders to tweak the fix and get

it perfect

Using the Adjustment Brush

The Adjustment Brush provides the ability to make targeted adjustments to only the areas in your image that need them Camera Raw does this by creating a mask over everything but the selected areas and making adjustments over that mask, similar to the way adjustment layers work inside Photoshop

Selecting the Adjustment Brush opens the Adjustment Brush panel and sets the Mask option

to New, as shown in Figure 8.28 The Adjustment Brush works differently from anything in Photoshop, using pins instead of layers to mark each adjustment The number of adjustments made depends entirely on how you use the Mask options

Trang 5

FIGURE 8.28

The Adjustment Brush panel provides a limited number of adjustments that can be made to targeted areas

of your image

Mask options

Adjustment options

Brush options

Mask overlay color

Setting the Mask options

The Mask options include New, Add, and Erase Whenever New is selected, a brush stroke over your image creates a new mask with new settings and places a new pin After the first brush stroke, the Mask option automatically changes to Add When Add is selected, the brush strokes you make are added to the currently selected mask You also can select Erase, which allows you to use the brush to erase areas in the currently selected mask

Note

Don’t be confused by all this talk of brushing on a mask You are probably wondering how an adjustment can

be applied through a mask Actually, each new mask is applied to the entire image and the Adjustment Brush

erases portions of it so the adjustment can filter through n

Using the pins

The pins that are placed every time a mask is created with the adjustment brush are only general indicators of the area where the adjustment is taking place A pin is placed at the beginning of the first stroke you make in creating a new mask To see the areas that are being affected by your adjustment, hover over the center of a placed pin, and the mask temporarily appears over the adjusted areas Figure 8.29 shows an image with two pins placed The pin on the moon is outlined
