386 Chapter 24

General Preferences (A, next page)

As the default Color Picker, choose Adobe (the

default setting) or the color picker for your system

For the onscreen HUD (Heads-Up Display) Color

Picker, choose a strip or wheel style and a display

size.★ See page 186

Choose a default Image Interpolation option for

Photoshop features, such as the Image Size dialog

and the Crop tool, that involve resampling or

transforming: Nearest Neighbor (Preserve Hard

Edges), the fastest and the best for hard-edged

graphics but the least precise; Bilinear, medium

quality; Bicubic (Best for Smooth Gradients),

higher quality but slower; Bicubic Smoother (Best

for Enlargement); or Bicubic Sharper (Best for

Reduction) The latter two options also produce

high-quality results

Options

Check Auto-Update Open Documents to have

open Photoshop documents that you edit in other

applications update automatically when you return

a file in Bridge

Check Beep When Done to have a beep sound

handy for commands that take a while to process

(so you can grab a snack!)

Check Dynamic Color Sliders to have the colors

above the sliders on the Color panel update as the

sliders are moved

Check Export Clipboard to retain the current

Clipboard contents on the system’s Clipboard

you uncheck this option (as we do), you can cycle

through related tools simply by pressing their

assigned letter (without pressing Shift) To learn

the tool shortcuts, see pages 104–106

Check Resize Image During Place to have pixel

images from other Photoshop files or other

applica-tions scale to fit the current canvas area

automati-cally when imported via the File > Place command

Check Animated Zoom for smooth, continuous

zooming when you change the zoom level by drag-ging (OpenGL is required and must be enabled in the Performance panel of this dialog)

With Zoom Resizes Windows checked, a floating

document window will resize when you change the zoom level via the Ctrl/Cmd- + (plus) or Ctrl/

Cmd- – (minus) shortcut or the Zoom tool This preference can be set either here or via the Resize Windows to Fit check box on the Options bar

level by scrolling the wheel

Check Zoom Clicked Point to Center to center the

image, when zooming, at the location you click

image to quickly float across the screen when you drag it with the Hand tool a short distance, then release the mouse (OpenGL is required and must

be enabled in the Performance panel of this dialog)

Check Place or Drag Raster Images as Smart Objects to have raster images that are imported

into Photoshop via the Place command arrive as Smart Object layers.★

History Log Check History Log to generate a log of your

Photoshop activity from each work session For

Save Log Items To, choose where the log is to be

saved: to the Metadata of a file, to a separate Text File, or to Both (of the above) For either of the latter two options, choose a location for the text file in the dialog that opens automatically, then click Save (or open the dialog by clicking Choose)

From the Edit Log Items menu, choose what data

is to be saved in the log: Sessions Only to log only when you launch or exit/quit Photoshop and which files were opened; Concise to log Sessions infor-mation plus a list of edits (states on the History panel); or Detailed, to include all of the above data plus any actions used and the options and param-eters used in each editing step These log options can be handy if you need to keep a tally of billable hours for clients or a record of your exact editing steps

General

To customize the colors for any of the three

Photoshop screen modes — Standard Screen Mode,

Full Screen with Menus, or Full Screen — choose a

background color from the first menu and a border

style (or None) from the second See page 94

Check Show Channels in Color to display RGB or

CMYK channels in color when displayed

individu-ally on the Channels panel (in the thumbnails),

and in the document window With this option

off, individual channels display in grayscale; this

can be useful for judging the luminosity values of

individual channels

Check Show Menu Colors to enable the display of

background colors that are assigned to menu

com-mands via Edit > Menus or by choosing a

work-space that contains them, such as the “New in CS5”

workspace

Check Show Tool Tips to allow the name or

func-tion of whichever bar, dialog, or panel feature the

pointer is currently hovering over (with the mouse

button up) to appear briefly onscreen so you can

identify it This is a good way to learn the names

and shortcuts for tools

Mac OS users: Check Enable Gestures if you have

a Windows 7 or MacBook computer with a

multi-touch trackpad (or are using a Magic Mouse with

an Apple computer) and you want to enable the

capability of the trackpad to zoom, rotate, or flick

images.★ Unlock this option if you find that the

gestures are causing unwanted changes

Panels & Documents

If Auto-Collapse Iconic Panels is checked and you

open a collapsed panel, it will collapse back to an

icon when you click outside it With this option

unchecked, the panel will remain expanded See

pages 96–97

Check Auto-Show Hidden Panels to allow panel

docks that you have hidden via the Tab or Shift-Tab shortcut to redisplay temporarily when you let the pointer pause on the dark gray vertical bar

at the left or right edge of the Application frame

if the document is in Standard Screen mode, or at the edge of your monitor if your document is in either of the Full Screen modes When the pointer

is moved away from the panels, they will disappear again

Check Open Documents as Tabs to have

documents dock automatically as tabs when opened instead of in a floating window (With this option checked in the Mac OS, images dock

as tabs in one document window even when the Application frame is hidden.)

Enable Floating Document Window Docking to

allow a floating document window to be docked

as a tabbed window when you drag its title bar below the bar at the top of the Application frame

or below the title bar of another window

Click Restore Default Workspaces to restore any

predefined Adobe workspaces to the Workspace menu that were deleted.★

Photoshop, from the UI Language menu, choose

a language for the interface

From the UI Font Size menu, choose Small (the

default choice that we prefer), Medium, or Large

as the font size for the Photoshop user interface (menus, panels, tool tips, the Options bar, and the like)

Check Prefer Adobe Camera Raw for Supported

Raw Files to have raw files that you open via File >

Open open into Camera Raw, as opposed to other

conversion software (we keep this option checked)

Keep Ignore EXIF Profile Tag unchecked to allow

Photoshop to read a camera’s EXIF metadata color

space information when opening files This option

was necessary only for some early digital cameras

Check Ask Before Saving Layered TIFF Files to

have an “Including layers will increase file size”

alert appear when layered files are saved in the

TIFF format You can use this as a reminder to

uncheck the Layers option in the Save As dialog

A File Handling Preferences

The Maximize PSD and PSB File Compatibility

option includes a flattened version of files in those formats to make them compatible with programs that don’t read Photoshop layers (including Adobe Lightroom) This option increases the file size but

is often a necessity Choose Ask to have the com-patibility option be offered via an alert when files are saved, or choose Always to produce compatible files upon saving without an alert appearing See pages 24 and 26

Note: Upon saving a layered file, if Ask is the cur-rent Maximize PSD and PSB File Compatibility preference and you check Maximize Compatibility and Don’t Show Again in the Photoshop Format Options dialog, Photoshop will switch the prefer-ence setting to Always If you uncheck Maximize Compatibility but do check Don’t Show Again in the alert, the preference setting will be switched

to Never.★
