Creating document presets





If you tend to use the same document size, color
mode, or other settings repeatedly in the New
dialog, take the time to create a document preset
for those settings. ereafter, you’ll be able to access
your settings via the Preset menu, which will save
you startup time as you create new les.
To create a document preset:
1. Choose File > New or press Ctrl-N/Cmd-N. e
New dialog opens.
2.
Choose settings, such as the width, height, reso-

lution, color mode, bit depth, background con-
tents, color prole, and pixel aspect ratio. Ignore
any setting that you don’t want to include in the
preset; you’ll exclude it from the preset in step 5.

Saving your file

If you’re not sure which format to use when saving
a le for the rst time, you can safely go with the
native Photoshop format, PSD. One good reason to
do so is that PSD les are more compact than TIFF
les (see also the sidebar on the following page).
To save an unsaved document:
1. If the document window contains any imagery,
you can choose File > Save (Ctrl-S/Cmd-S); if it’s
completely blank, choose File > Save As (Ctrl-
Shift-S/Cmd-Shift-S). e Save As dialog opens.
2.
Type a name in the File Name eld
A
/Save As
eld (
A
, next page).
3.
Choose a location for the le.
In Windows, if you need to navigate to a dier-
ent folder or drive, use the Save In menu at the
top of the dialog.
In the Mac OS, click a drive or folder in the
Sidebar panel on the left side of the window.

To locate a recently used folder, use the menu
below the Save As eld.
4.
Choose a le format from the Format menu.
Only the native Photoshop (PSD), Large











Document Format (PSB), TIFF, and Photoshop
PDF formats support layers (see the informa-
tion about attening layers on pages 134 and
146).
5.
If you’re not yet familiar with the features
listed in the Save area, leave the settings as is.
e As a Copy option is discussed on page 26.
6.
If the le contains an embedded color prole
and the format you’re saving to supports
such proles, in the Color area, you can check
ICC Profile/Embed Color Profile: [prole
name] to save the prole with the le. (To

learn about embedded proles, see pages 10,
13, and 16.)
7.
Click Save.
➤ In the Mac OS, to have Photoshop append a
three-character extension (e.g., .tif, .psd) to the
le name automatically when a le is saved for
the rst time, in Edit/Photoshop > Preferences >
File Handling, choose Append File Extension:
Always. Extensions are required when export-
ing Macintosh les to the Windows platform
and when posting les to a Web server.
➤ To learn about the Maximize PSD and PSB File
Compatibility option in the File Handling panel
of the Preferences dialog, see page 390.

Once a le has been saved for the rst time, each
subsequent use of the Save command overwrites
(saves over) the last version.
To save a previously saved file:

Choose File > Save (Ctrl-S/Cmd-S).
e simple Revert command restores your document
to the last-saved version.
Note: We know you can’t learn everything at once,
but keep in mind for the future that the History
panel, which Chapter 10 is devoted exclusively to,
serves as a full-service multiple undo feature. Also,
a use of the Revert command shows up as a state on
the History panel, so you can undo a revert by click-
ing an earlier history state.
To revert to the last saved version of a file:
Choose File > Revert.
➤ To undo the most recent modication, choose
Edit > Undo (Ctrl-Z/Cmd-Z). Not all edits can be
undone by this command. For the other undo
and redo commands, see page 113.
CHOOSING THE CORRECT FORMAT
Photoshop (PSD), Large Document (PSB), TIFF, and
Photoshop PDF are the only formats that preserve
the following Photoshop features:
➤ Multiple layers and layer transparency
➤ Shape layers
➤ Smart Objects
➤ Adjustment layers
➤ Editable type layers
➤ Layer effects
➤ Alpha channels
➤ Grids and guides
ICC color management profi les are preserved by the
above-mentioned formats (and also by the JPEG

and Photoshop EPS formats).
To prepare your document for printing from another
application or to export it to an application that
doesn’t read Photoshop layers, read about the TIFF,
EPS,and PDF formats on pages 417–420. Or for Web
output, read about the GIF and JPEG formats on
pages 421–426.

e Save As command lets you save a copy of your
le under a new name (say, to create a design, docu-

ment color mode, or adjustment variation) or with
dierent options. Another important use of this
command is to save a attened copy of a le in a dif-
ferent format, for export to another application. is
is necessary because most non-Adobe applications
can’t import Photoshop PSD les or read Photoshop
layers.
To save a new version of a file:
1. Choose File > Save As (Ctrl-Shift-S/Cmd-
Shift-S). e Save As dialog opens.
2.
Change the name in the File Name/Save As eld.
 i s i s i m p o r t a n t !
3.
Choose a location for the new version from
the Save In menu in Windows or by using the
Sidebar panel and columns in the Mac OS. (Read
about the new Save As to Original Folder prefer-
ence on page 390.
★
)
4.
Optional: From the Format menu, choose a dif-
ferent le format. Only formats that are available
for the le’s current color mode and bit depth
are listed. Note: If you try to save a 16-bit le in
the JPEG (.jpg) format, Photoshop will produce a
attened, 8-bit copy of the le automatically.
★
Beware! If the format you’ve chosen doesn’t sup-

port layers, the Layers option becomes dimmed,
a yellow alert icon displays, and layers in the new
version are attened.
A DESIGNER’S BEST FRIEND
To create document variations within the same fi le,
explore the Layer Comps panel; see pages 382–384.










5.
Check any available options in the Save area, as
desired. For example, you could check As a Copy
to have the copy of the le remain closed and
the original le stay open onscreen, or uncheck
this option to have the original le close and the
copy stay open.
Depending on the current File Saving settings
in Edit/Photoshop > Preferences > File Handling
(and depending on whether you’re working on a
Windows or Mac OS machine), some preview and
extension options may be available in the Save
As dialog. See pages 389–390.
6.

In the Color area, check ICC Profile/Embed
Color Profile: [prole name], if available (see
pages 10, 13, and 16), to include the prole, for
color management.
7.
Click Save. Depending on the chosen le format,
another dialog may appear. For the TIFF format,
see page 417; for EPS, see pages 418–419; or
for PDF, see page 420. For other formats, see
Photoshop Help.
➤ If you don’t change the le name or format in
the Save As dialog but do click Save, an alert will
appear. Click Yes/Replace to replace the original
le, or click No/Cancel to return to the Save As
dialog.
➤ To optimize a le in the GIF or JPEG format for
Web output, see pages 423–426.
