Unlike the Clone Stamp tool, which merely copies

a source color without blending it into the target

area, the three tools discussed next sample a texture,

apply it to the target area, and blend the texture into

the existing color and brightness values With these

tools, it’s easy to fix imperfections such as facial

blemishes or paper creases in a vintage photo, and

the results are usually seamless

With the Healing Brush tool, you Alt-click/

Option-click to sample from an unblemished area,

then apply strokes to repair the blemish.AThe

blemish pixels are replaced with the sampled pixels

With the Patch tool, you select the blemish

area first, then drag the selection marquee over

an unblemished area to sample it Here again, the

blemish pixels are replaced with the sampled ones

And with the Spot Healing Brush tool, you simply

stroke over blemishes without sampling Pixels

are replaced almost magically based on data from

neighboring pixels

Using the Healing Brush tool

To use the Healing Brush tool:

1 Choose the Healing Brush tool (J or Shift-J)

2. Create a new, blank layer

3 Optional: To confine the repair to a specific area

and to prevent the Healing Brush from

pick-ing up colors from neighborpick-ing areas, create a

selection with the Lasso tool

4. On the Options bar,B do all of the following:

Click the Brush picker arrowhead, and choose a

high Hardness value (Also, in Edit/Photoshop >

Preferences > Cursors, click Full Size Brush Tip.)

Choose Mode: Normal to preserve the grain,

texture, and noise of the area surrounding the

target; or if you don’t need to preserve those

attributes, choose a different mode, such as

Lighten for subtle retouching or to correct

wrinkles or creases that are very close together,

to prevent them from cloning onto one another

Click Source: Sampled.

Because you will be working on a new, blank

layer, from the Sample menu, you should choose A We will soften the crow’s feet around the eyes in this

portrait photo.

B We chose these Options bar settings for the Healing Brush tool.

All Layers to sample pixels from all the layers

below the pointer

Check Aligned to maintain the same distance

between the source point and the area that you drag across, even if you release the mouse between strokes, or uncheck this option to resample from the original source point each time you release the mouse

If you’re using a stylus and tablet, click the

Tablet Pressure Controls Size button and

from the Size menu on the Brush Preset picker,

choose Pen Pressure or Stylus Wheel.★

Click the Toggle Clone Source panel button, then check Show Overlay and Clipped on

the panel

5 Press [ or ] to scale the brush to suit the area to

be cloned

6. Alt-click/Option-click an area to sample it as the source texture (A, next page) The sampled area displays inside the brush cursor

7 With the new, blank layer still selected, drag

across the area to be repaired.BWhen you

release the mouse, the source texture will be

applied to the target area and will be blended

with neighboring pixels It will render in two

stages, so be patient.C–D

8 To establish a new source point for further

repairs, Alt-click/Option-click a different area,

then apply more strokes (you can change the

diameter of the brush tip)

9 Optional: To make the results more subtle,

lower the opacity of the new layer slightly to blend it with the original image layer

➤ To correct mistakes made with the Healing Brush tool, hide the image layers below the new layer that you applied strokes to so you’ll be able to see your strokes more easily, then with the Eraser tool, erase the unwanted strokes

This is easier than stepping back through states

on the History panel

C The area around the eye on the right now looks smoother.

A With the Healing Brush tool, we held down Alt/Option

and clicked the area to be used as replacement pixels… B … then dragged across the area to be repaired Note

that the brush tip is separate from the sampling pointer.

Brush tip Sampling pointer

D Our retouching brush strokes are on a separate layer that we named “healing brush.”

C With Darken chosen as its Mode, the tool repaired only

the light areas of skin Now her nose looks less shiny

B Drag once or twice over a hot spot, letting your stroke(s) follow the natural contours of the face.

A The Healing Brush tool is also handy for removing

shiny hot spots from a portrait, which are caused by

harsh, uneven lighting Choose Mode: Darken on the

Options bar for the tool, then Alt-click/Option-click to

sample a medium-tone area of skin.

REMOVING FACIAL HOT SPOTS

PUPPET WARP

To apply reshaping to areas of an image (perhaps to slim a neck or chin in a portrait), try using the Puppet Warp command (see pages 314–315)

Using the Spot Healing Brush tool

Sampling an area correctly for a repair can be

dif-ficult in tight areas, such as folds of skin, which

tend to be close together and have highlights and

shadows With the Spot Healing Brush tool, no

sampling is required It’s an effective blemish and

wrinkle remover (and it’s cheaper than Botox!)

To use the Spot Healing Brush tool:

1 Do either of the following:

Duplicate the Background by pressing Ctrl-J/

Cmd-J, and keep the duplicate layer selected

Create a new, blank layer to contain your

correction strokes, and keep it selected

2 Choose the Spot Healing Brush tool (J or

Shift-J), and zoom the document to 100%

3 In Edit/Photoshop > Preferences > Cursors,

under Painting Cursors, click Full Size Brush

Tip and check Show Crosshair in Brush Tip

4 On the Options bar, do the following:

Choose a Mode For preserving skin tones,

we’ve achieved good results with Normal and

Lighten modes When used with Replace mode,

the tool may pick up unwanted facial details in the stroke, such as hair or eyelashes

To help preserve the existing tonal values, such

as in skin tones, click Type: Create Texture.

(For the Content-Aware option, see the next three pages.)

To allow the brush to sample pixels from all

the layers below the pointer, check Sample All

Layers (check this option if you created a new,

blank layer in step 1), or uncheck this option

if you’re working directly on an image layer

5 Make the brush slightly wider than the area

to be repaired (such as a crease) by pressing [ or ], then drag once along it.A–BRepeat to repair other areas.CWe’ve found that a small brush produces the most seamless repairs

6 Optional: To make the results look more subtle,

lower the opacity of the new layer slightly to blend it with the original image layer

➤ If you applied the Spot Healing strokes to a separate layer, you can erase any unwanted strokes from that layer

AWith the Spot Healing Brush tool, we’re dragging along a crease.

B The creases we dragged over are smoothed out C The creases are removed.

USING THE CONTENT-AWARE OPTION WITH THE SPOT HEALING BRUSH TOOL ★

In the right scenario, the Spot Healing Brush tool, used with its Content-Aware option, can be quick, easy, and

powerful When used to remove an object from a photo, it works better if the object being removed has small random

shapes around it (such as foliage, water, or clouds in a landscape) A–Cthan if the surrounding area contains

isolated, distinct objects This tool and option also work well for repairing tears or scratches in a vintage photo

A We want to remove the hydrant from this image.

C Poof! To supply the replacement pixels, the Spot Healing Brush tool analyzed and sampled pixels from neighboring areas This is as easy as retouching gets

B For the Spot Healing Brush tool, we chose a brush

Hardness of 100% and Normal mode, and clicked

the Content-Aware option We made the brush a

medium size, then with one continuous stroke, we

covered the hydrant and its shadow

A We want to zap the barn from this photo.

B For the Spot Healing Brush tool, we chose a brush Hardness of 100% and Normal mode, and clicked the Content-Aware option We made the brush a medium size, then covered the barn with one continuous stroke

C On this photo, we ran into

a glitch: The automatic healing process that the tool performed left behind a red tint from the original object To see how we were able to apply a successful content-aware repair without healing, see the following page.

Continued on the following page

USING THE CONTENT-AWARE OPTION FOR THE FILL COMMAND ★

On this page, you’ll see an unsuccessful use of the Content-Aware option with the Spot Healing Brush

tool,A–Cand on the next page, you’ll see a successful alternative solution (A–C, next page)

C The content-aware fill successfully removed the barn without leaving behind a reddish tint, because no healing was involved.

➤ To achieve a similar result with the Spot Healing Brush tool, use it with Replace mode chosen and the Content-Aware option clicked on the Options bar.

A Via Undo, we removed the Spot Healing Brush edit from the photo so we could try a dif-ferent approach Our first step was to create a loose selection of the barn with the Lasso tool.

B Next, we chose Edit >

Fill In the dialog, we chose Use: Content-Aware, Mode:

Normal, and Opacity: 100%, then clicked OK
