Getting Rid of Your
Empty Layers Fast
In CS5, Adobe included a built-in script
that will go through your Layers panel
and remove any empty layers (layers
with nothing on them) automatically (once you get a large multi-layered project going, you wind up with more
of these than you’d think) To have Photoshop tidy things up for you, go under the File menu, under Scripts,
and choose Delete All Empty Layers.
Removing Noise from Cell Phone Photos
Since Photoshop is a pro tool, most
of us probably wouldn’t even think
of using Camera Raw’s built-in Noise Reduction feature to remove the noise from our cell phone camera’s photos, but…why not? Cell phone photos are notorious for color noise, which Camera Raw cleans up really well
Try it one time, and I’ll bet you’ll use
it more than you ever dreamed (to open a cell phone photo in Camera Raw, just find it on your computer in Mini Bridge, then Right-click on it and
choose Open in Camera Raw).
Using the HUD Pop-Up Color Picker
If you’ve ever thought, “There’s got
to be an easier way to pick colors than clicking on the Fore ground color swatch every time,” you’re gonna love this: It’s a pop-up Color picker (Adobe calls it the HUD [Heads-Up Display], because you keep your eyes on the image, instead of looking over and down
at the Foreground/Background color swatches) First, choose a Brush tool,
then just press Command-Option-Ctrl (PC: Alt-Shift) and click (PC:
Right-click) on your image It brings
up a simplified color picker where you can quickly choose your color (I find it easier if you choose the hue first, from the bar on the right, then choose the tint and saturation of the color from the box on the left)

Trang 3Chapter 9 Fixing Common Problems
The title for this chapter comes from the 2009 movie Little
Problems (written and directed by Matt Pearson), but
I could have just as easily gone with the 2008 short Little
Problems (written and directed by Michael Lewen), but
there was one big thing that made the choice easy The
first movie was about zombies You just can’t make a bad
movie about zombies It’s a lock Throw a couple of hapless
teens (or in this case “an unlikely couple”) into some
deso-lated location with a couple hundred flesh-starved un dead,
and you’ve got gold baby, gold! Now, has anyone ever
won-dered, even for a second, why every zombie in the rich and
colorful history of zombies, has an insatiable hunger for
human flesh and only human flesh? Why can’t there be
zombies that have an insatiable hunger for broccoli? Then,
in their bombed-out shell of a desolate vacant city, on every
corner there would be other zombies selling broccoli the
size of azalea bushes Anyway, it’s just a little too coinci-dental that every zombie wants to eat you, but they don’t want to eat something that might actually keep them alive, and is in ample and easy reproducible supply, like broccoli,
or spring rolls, or chowder Nope, it has to be human flesh, even though you know and I know (say it with me) it tastes like chicken (well, that’s what I’ve been told, anyway)
Another thing that drew me to the first Little Problems
was the director’s last name, seeing as all my books are published by subsidiaries of Pearson Education, a company who somehow chose to hire Ted Waitt as my editor, despite the fact that they were forewarned by the DCBGC (the Desolate City Broccoli Growers’ Consortium) that Ted might not actually be the strict vegetarian he claimed to be in his resume I probably shouldn’t say anything bad about Ted, though I don’t want to bite the hand that feeds me
Little Problems

You can shoot outside all day and be getting shots that look just great, but step indoors and everything changes The culprit is Auto white balance (the default setting on digital cameras, and most people never change from this default) With Auto white balance, shooting indoors (like the interior shot shown below) you get what you see here—a photo that looks way too yellow (or if I had shot in an office, where the standard is fluorescent lighting, it would be too blue) Here are three different ways to deal with the problem:
Step One:
Here’s a photo taken in the lobby of a
hotel and, of course, it has the type of
lighting you’re likely to find in a lobby
(or a home), called “tungsten lighting”
(by photographers and people who sell
lighting for a living), which is why the
color in the photo looks so yellow (pretty
typical for shots taken indoors when
your white balance set to Auto) The first
method is to add a blue Photo Filter
ad-justment to offset the yellow and make
the color look more natural, so click on
the Photo Filter icon in the Adjustments
panel (it’s shown circled here)
Step Two:
Just a heads up: when you choose Photo
Filter, the default filter is yellow, so your
photo looks even worse at first, but that’s
easy to fix From the Filter pop-up menu,
choose Cooling Filter (82), as seen here,
and then drag the Density (amount) slider
to the right until the image looks more
natural Here, I dragged it over to 50%
(the amount will be different depending
on the photo, so this is a judgment call
you’ll have to make) This correction looks
okay, but if you have the original RAW
image, you can get a much better
correc-tion than this using Camera Raw
Three Ways to
Fix the Color in
Indoor Shots
Trang 5The Adobe Photoshop CS5 Book for Digital Photographers
Step Three:
If you took the original shot in RAW,
this is the best case scenario, because
you’ll usually get much better results
by opening the image in Camera Raw
and choosing one of the built-in
pre-sets in the White Balance pop-up menu,
like Tungsten (shown here), which
pret-ty much fixes the problem, and does
it without washing out the red color
in the chairs (if you look back at the
image in Step Two, the chairs lost some
of the saturation in the reds It was a
fair trade—to lose some of the red to
get the rest of the color fixed—but this
method, with a RAW photo, is much
better all around) In short: you’ll get
better results fixing the white balance
of RAW images in Camera Raw than
you will for JPEG or TIFF images
Step Four:
If your original shot was taken as a JPEG
or TIFF, you can still use Camera Raw to
adjust your white balance, but the results
won’t be as good as if it had been shot in
RAW Click on the photo in Mini Bridge,
then Right-click on it and choose Open
in Camera Raw When it opens, you’ll
see that something’s missing—there is no
Tungsten preset for JPEGs or TIFFs, only
As Shot and Auto (Auto seems to look
okay as a starting place for this photo,
but I had to drag the Temperature slider
to the left a bit to remove more of the
yellow, and it still doesn’t look as good as
the simple Tungsten preset used on the
RAW image in Step Three) Your other
choice is to get the White Balance tool
and click on a light gray area in the photo
(I tried this, as well, and in this case, it
looked worse than the Auto preset)

Step One:
Open a photo where your subject is
in the shadows (it can be a person, or
a building, or anything backlit) In this
example, the light is coming from the
windows behind our subject, so he
ap-pears almost like a silhouette Ideally,
we’d like to brighten him up, and darken
the light from the windows and the wall
to the right by pulling back the
high-lights To do this, first go under Filter
menu and choose Convert for Smart
Filters This lets you apply the
adjust-ment as if it was an adjustadjust-ment layer
(meaning you can re-edit it later if you
need to, or even delete the adjustment
altogether) Even though the adjustment
we’re going to apply isn’t found under
the Filter menu, for some reason Adobe
lets it act like it is a regular filter, so why
not take advantage of it, eh? Now go
under the Image menu, under
Adjust-ments, and choose Shadows/Highlights.
When Your Subject Is in
the Shadows
We all wind up shooting subjects that are backlit (where the light is behind your subject) That’s because our eyes automatically adjust to the situation and we see the subject just fine in our viewfinder The problem is our cameras aren’t nearly
as sophisticated as our eyes are, so you’re almost guaranteed to get some shots where the subject is way too dark Although I feel you get better results using Camera Raw’s Fill Light and Recovery sliders, Shadows/Highlights does a fairly decent job, and there’s a trick you can use to make the adjustment re-editable
Trang 7The Adobe Photoshop CS5 Book for Digital Photographers
Step Two:
If you’re choosing Shadows/Highlights, you
probably have a problem in the shadow
areas, which is why, by default, it’s set to
open up (lighten) the shadow areas in
your photo by 35% (as seen here) In
pre-vious versions of Photoshop, the default
setting was 50%, but most users felt it was
too high a setting, so in CS5, Adobe set
it down to something more reasonable
However, in this case, our subject is so
bur-ied in the shadows that we’ll have to open
the shadows quite a bit, but the problem
with opening the shadows 50% or more
is your photos tend to look “milky.” To
get around that, turn on the Show More
Options checkbox, as shown here
Step Three:
This brings up an expanded version of the
dialog (as shown here) I have a little
for-mula that I use that usually gives me the
opened up shadow areas I need, with out
looking totally fake First, I usually leave
the Amount some where around 35% (the
final amount depends on the individual
photo, and here I had to increase it to 75)
Then, I drag the Shadows Radius slider to
the right to between 65 and 80 (as shown
here), which smoothes out the effect even
more (The Radius amount determines
how many pixels each adjustment affects,
so to affect a wider range of pixels,
in-crease the amount.)
TIP: Save a New Default
If you come up with some settings you
like, click the Save As Defaults button
in the bottom-left corner of the dialog,
and now it will open with your settings
Trang 8228 Chapter 9 Fixing Common Problems
The Adobe Photoshop CS5 Book for Digital Photographers
Step Four:
Now that the shadows are opened up
(and look reasonably realistic), you can
work on the highlights In most cases,
you’ll only have to fix one or the other—
the shadows or the highlights, but not
both It takes someone special to actually
take a photo that is so wrong on every
level that it needs both areas adjusted
(like I did here) So, to pull back (darken)
the highlights in the window and on the
wall on the right, go to the High lights
section and drag the Amount slider to
the right (as shown here) Now, if later
you need to tweak these changes,
be-cause in Step One you applied this as
a Smart Filter, you can go to the Layers
panel, double-click directly on the words
“Shadows/Highlights” (as shown here),
and the Shadows/Highlights dialog will
appear again, with the settings you used
previously Just make any changes you
want, then click OK
Before After (opening up the shadows and pulling back
the highlights)

Step One:
Here’s a shot taken in Beijing’s Tiananmen Square, and the sky is that flat gray that
we all hate for travel and outdoor shots
Before we go any farther, the first thing
I usually try is to press Command-L (PC:
Ctrl-L) to open the Levels dialog, and
darken the midtones by dragging the cen-ter Input Levels slider (circled here in red)
to the right If there is any detail in the sky
we can’t see, this will usually do the trick, but unfortunately for this image, it just made the gray, grayer, so once I tried it,
I hit Cancel instead of OK Of course, to adjust the sky, you’ll have to select it first
You can use any selection tool you’re comfortable with, but for something simple like this, I usually just use the
Magic Wand tool (press Shift-W until
you have it; it’s nested with the Quick Selection tool)
Nothing ruins an outdoor shot like a dull gray sky (well, except for one
other thing—later in this chapter, you’ll learn how to remove tourists), but
luckily, in many cases, you can save the shot by darkening the midtones a bit,
and adding a blue tint or gradient to the sky Here’s how to do both:
Fixing Shots with
a Dull Gray Sky
Trang 10230 Chapter 9 Fixing Common Problems
The Adobe Photoshop CS5 Book for Digital Photographers
Step Two:
Click the Magic Wand tool on the gray
sky to select it I set my Tolerance (up
in the Options Bar) to 10, so it doesn’t
accidentally select the buildings at the
bottom of the image, as well (when I
tried my usual Tolerance setting of 20,
it selected too much) At 10, one click
won’t select the entire sky, so
press-and-hold the Shift key and click in any areas
it didn’t select (it may take you a few
Shift-clicks to get the whole sky selected)
Now, although this isn’t exactly what this
project is about, you could paste a
to-tally different image of clouds into this
selected area You’d do that by opening
a photo of clouds, pressing Command-A
(PC: Ctrl-A) to Select All, then pressing
Command-C (PC: Ctrl-C) to Copy that
image into memory Then, you’d switch
back to the first image, go under the Edit
menu, under Paste Special, and choose
Paste Into to paste the clouds into your
selected area
Step Three:
Instead, we’re going to open a photo that
has a sky color we like (you can download
this same photo, and most of the key
pho-tos used in this book, at the Web address
listed in the introduction at the front of
the book) Once you open the image,
switch to the Eyedropper tool (I), and
click once on the darkest blue area in the
image (as shown here) to make that your
Foreground color Now, press the letter X
to swap your Foreground and Background
colors, then click the Eyedropper on the
brightest blue in the photo (lower in the
sky), so that now your Foreground is a
lighter blue, and your Background is a
darker blue
