Saving your file

If you’re not sure which format to use when saving

a file for the first time, you can safely go with the

native Photoshop format, PSD One good reason to

do so is that PSD files are more compact than TIFF

files (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) The Save As dialog opens

2 Type a name in the File Name field A /Save As

field (A, next page)

3. Choose a location for the file

In Windows, if you need to navigate to a

differ-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 field

4 Choose a file 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 flattening 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

The As a Copy option is discussed on page 26

6 If the file contains an embedded color profile

and the format you’re saving to supports

such profiles, in the Color area, you can check ICC Profile/Embed Color Profile: [profile

name] to save the profile with the file (To learn about embedded profiles, 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 file name automatically when a file is saved for the first time, in Edit/Photoshop > Preferences >

File Handling, choose Append File Extension:

Always Extensions are required when export-ing Macintosh files to the Windows platform and when posting files 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

A This is the Save As dialog in Windows.

Once a file has been saved for the first 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).

The 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 modification, 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

A This is the Save As dialog in the Mac OS.

26 Chapter 2

The Save As command lets you save a copy of your

file under a new name (say, to create a design,

docu-ment color mode, or adjustdocu-ment variation) or with

different options Another important use of this

command is to save a flattened copy of a file in a

dif-ferent format, for export to another application This

is necessary because most non-Adobe applications

can’t import Photoshop PSD files or read Photoshop

layers

To save a new version of a file:

1 Choose File > Save As

(Ctrl-Shift-S/Cmd-Shift-S) The Save As dialog opens

2 Change the name in the File Name/Save As field

This is important!

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 file format Only formats that are available

for the file’s current color mode and bit depth

are listed Note: If you try to save a 16-bit file in

the JPEG (.jpg) format, Photoshop will produce a

flattened, 8-bit copy of the file 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 flattened

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 file remain closed and the original file stay open onscreen, or uncheck this option to have the original file 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: [profile name], if available (see

pages 10, 13, and 16), to include the profile, for color management

7. Click Save Depending on the chosen file 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 file name or format in the Save As dialog but do click Save, an alert will appear Click Yes/Replace to replace the original file, or click No/Cancel to return to the Save As dialog

➤ To optimize a file in the GIF or JPEG format for Web output, see pages 423–426

Using the Status bar

Using the Status bar and menu at the bottom of the

document window, you can read data about the

cur-rent file or find out how Photoshop is curcur-rently using

memory

To use the Status bar:

From the menu next to the Status bar at the

bottom of a floating or tabbed document window,

choose the type of data you want displayed on

the bar:

Document Sizes to list the approximate file

stor-age size of a flattened version of the file if it were

saved in the PSD format (the value on the left)

Document Profile to list the embedded color

profile (the words “Untagged [RGB or CMYK]”

appear if a profile hasn’t been assigned).A

dimensions (its width, height, and resolution)

Scratch Sizes to list the amount of RAM

Photoshop is using to process all currently open

files (the value on the left) and the amount of

RAM that is currently available to Photoshop (the

value on the right) If the first value is greater

than the second, it means Photoshop is currently

utilizing virtual memory on the scratch disk

Efficiency to list the percentage of program

operations that are currently being done in RAM

as opposed to the scratch disk (see page 391)

When this value is below 100, it means the

scratch disk is being used

Current Tool to list the name of the current tool.

To view detailed data about a particular file, use the

Metadata panel in Bridge

To find out the storage size (and other data)

of a file:

1 On the Application bar in Photoshop, click
