If you follow along, youll want to make sure that you are masking
in Additive mode (with the plus selected on the property bar).
That way, each click with the wand will grow the mask, not replace what
was previously done.
With a Tolerance setting of 12, we were able to mask most of the boy
in just five clicks.

You can see that we didnt get all of him, and we got a bit of the
sidewalk (the dark parts). Also, the bill of his hat is too much pattern
for the Magic Wand to handle, but these flaws will be fixed in clean-up
with the Mask Brush toolan inevitable part of the process. By zooming
in and drawing around the periphery of the boy, we reached this stage
in a scant five minutes.

Youll notice that there are plenty of little holes in the mask,
and we did that intentionally. We only concerned ourselves with the perimeter
of the childwe went around the bill of his hat, got his shoes, removed
the sidewalk between his feet, and made sure his neck made it within the
mask. We did not worry about filling in the entire mask, and heres
why:
- Mask Ø Shape Ø
Remove Holes
This command does just what it promises to doit removes any holes
that are inside of a mask. That one command can shave hours off of a project,
and we use it so often, we created a hotkey for it from Tools Ø
Options Ø Customize Ø
Shortcut Keys.

Now that our boy is masked, we can do something to him, like brighten
him up. But when we first did so (by going to Image Ø
Adjust Ø Brightness-Contrast-Intensity
and setting a Brightness value of 15), we didnt like what we saw
around the edge of his body. It was as if he was no longer part of the
photoeerily floating above it.
Thats when we turned to the Feather command. There are several
commands in PAINT called Feather; the one that pertains to masks applies
a bit of blending to the edges of a mask to help it integrate with the
background. That is precisely what we wanted, so we added 10 pixels of
feather, and that made all the difference in the world.
Finally, we carefully masked the boys face and applied five percentage
points of additional brightness to it. Compare Figure 25.9, the finished
image, with the dark original shown in Figure 25.8.
If you remember nothing else from this exercise, remember this:

Focusing Attention
Just like we brightened the boy, we can also affect the background of
an image. In Figure 25.10 (879035.wi from Nature), the
grapes and the leaves share the same color and tone, and the grapes dont
stand out very much. Also, the photographer used a fairly wide depth of
field, so the background leaves are almost as focused as the grapes.
FIGURE

the Brightness controls.
FIGURE
25.10 This is a pretty photograph, but if a
vineyard wanted it for an ad, it might want the grapes to stand out more.
We cant change the color of the leaves (although we suppose purple
grapes would not be out of the question), but we can blur the background
a bit, calling more attention to the grapes.
There is good news and bad news with respect to these grapes. The bad
news is that there is no automatic way to mask themtoo much detail
and not enough contrast. You will have to use the Freehand and Brush tools.
But the good news is that you do not need an exact mask; in fact, its
better if you dont. When you apply most of the blur effects, its
better if you not define such a sharp edge around the foreground and background.
Therefore, masking the grapes was a 30-second operation with the Freehand
Mask tool, and then one trip to Mask Ø
Shape Ø Smooth to fix any excessive
bumps that we made during the trip around the grapes.

Now we have the grapes masked...precisely the opposite of what we want.
To switch things around, go to Mask Ø
Invertnow the background is masked.
We chose a subtle Radial Blur (Effects Ø
Blur Ø Radial Blur Ø
Amount of 3), as it brought a bit more energy to the photoas if
the background was revolving around the grapes. This proved more dynamic
than the conventional Gaussian Blur. The final effect, Figure 25.11, doesnt
look like an actual untouched photograph, nor is it supposed to. It would
be used to call particular, and exaggerated, attention to the foreground
object.

25.11 When you really want an object to stand
out, blur everything else...
Local Motion
Todays cameras are so sophisticated, they can capture a moment
of time with utter precisionmaking it seem as if the entire world
has stopped. That is the case with Figure 25.12 (869077.wi
from Sprt_Fit). On this nice bright day, the shutter speed is so fast
that the bikers are motionless, and yet the camera lens is stopped down
so much that the entire foreground is in sharp focus, and even the clouds
and the mountains in the distance are almost in focus.
The more artistic effect would be if you, as photographer, were to use
a slow shutter speed and follow the bike riders with your camerakeeping
them in a constant position in your lens and allowing all other elements
to pass from left to right. This is tricky to do with the camera, but
easy to do in the digital darkroom.
FIGURE
25.12 Are they moving or standing still?
Our mission, therefore, is to mask the hill that the riders are on and
apply a Motion Blur to it. We could mask the hill manually, but well
introduce you to a different technique. This mask begins as a rectangle,
covering the width of the image and the highest point of the hill.

Then we reached for the Mask Transform tool, which for reasons entirely
unknown, resides on the Object Tools flyout (the first one on the toolbox),
not on the Mask Tools flyout. With that tool, we could shape the mask
as if it were a vector object, so we grabbed at the top-left corner and
dragged it down until it flattened out. That was the quickest way we could
think of to get to this point.

To shave the mask down to fit the hill, we turned to the trusty Mask
Brush tool, but before heading out to the image, we stopped at the property
bar to toggle Subtractive mode, turn the nib square, flatten it, and rotate
it to the approximate angle of the hill. Now we could shave the mask just
by sliding down it.

Now for the blur. The bike riders are heading to the left, and we are
following them in our camera lens, as if the hill they are on is moving
to the right. That is easily achieved with Effects Ø
Blur Ø Motion Blur and setting the
direction to the right and a distance of 20 pixels.

The screen image above was taken with the mask marquee turned off (Mask
Ø Marquee Visible toggle) so you can
better see the effect. The problem is the bicycle tiresthey are
blurred also, as they reside within the masked area. (They make it look
like the riders are riding on sand...a nice effect only if you want it.)
