Task 10 How to Set Photoshop Preferences

General Controls

Select Edit, Preferences, General to open the Preferences box to the General page (in Mac OS X, select Photoshop, Preferences, General). You use this page of the Preferences box to control interpolation, the Color Picker option, and a number of other general application parameters.

Preferences Title pop-up menu: Click the arrow to display a list of other pages in the Preferences box; select an option to open that page. Also, the Next and Prev buttons jump forward or backward to the choices in this list.

Color Picker pop-up menu: Click the arrow to display a list of Color Picker options; select the Adobe or Apple/Windows Color Picker.

Image Interpolation pop-up menu: Click the arrow to display a list of interpolation options. Select Nearest Neighbor, Bilinear, Bicubic, Bicubic Smoother, or Bicubic Sharper. In most cases, use Bicubic Smoother when enlarging an image and use Bicubic Sharper when reducing or downsampling. Each image is different, however, so experiment for best results.

UI Font Size: This option allows control over the size of text for user interface items such as the text that appears on the tabs of palettes. By default it is set to Small.

History States: By default this number is set to 20, which means Photoshop stores (via the History palette) the last 20 steps performed on an image. A larger number gives you greater control in how many steps you can go back (if needed), but the tradeoff is that it also requires more memory to store that information in the History palette.

Export Clipboard check box: This option attempts to export the current Clipboard contents when Photoshop is closed. Leave this option disabled because it slows the shutdown process and because the exported format is almost always incompatible.

Show Tool Tips check box: Activatesthe pop-up tool descriptions when you hover the cursor over the interface elements.

Zoom Resizes Windows check box: Resizes image windows when zooming in and out of the image from the keyboard.

Auto-Update Open Documents check box: Updates open documents automatically.

Show Menu Colors check box: Enables the color display for custom menus.

Resize Image During Paste/Place check box: Determines whether to resize pasted or placed images that are larger than the Photoshop document.

Beep when Done check box: Emits an audible beep when a task is complete.

Save Palette Locations check box: Reopens palettes in the same place and at the same size as they were when they were closed, or when Photoshop is closed.

Use Shift Key for Tool Switch check box: Enables the use of the Shift key along with the letter key assigned to the tool to toggle tool selections within a group of tools. When unchecked, simply repeatedly press the letter key assigned to the tool to toggle between the grouped tool selections.

Automatically Launch Bridge check box: Automatically launches Bridge in the background whenever Photoshop is opened.

Zoom with Scroll Wheel check box: This determines whether scrolling or zooming is the default action for a mouse with a scroll wheel option.

History Log check box: Enable this check box to generate an ongoing log of activities executed within each session of Photoshop.

Save Log Items to Metadata: Saves the history log in XML-base metadata format within the file.

Save Log Items to Text File: Saves the history log as a generic text file. Click the Choose button to designate the save location for the history log text file. Click and navigate to the desired destination folder.

Save Log Items to Both: Creates a history log record in both metadata and generic text formats.

Edit Log Items pop-up menu: Select from Concise, Detailed, and Sessions Only history log formats. Concise shows the opening and closing of files and of the application itself, plus the edits recorded in the History palette. Detailed shows everything Concise does, plus every edit used and the file paths. Sessions Only records only the start date and time, with no editing data stored.

Reset All Warning Dialogs button: Resets all warning messages to their defaults.

Use Lower Case check box: Adds the file extension using lowercase letters. In Windows, the File Extension pop-up menu offers the choice between automatically adding extensions to filenames in Use Upper Case or Use Lower Case letters.

Ignore EXIF Profile Tag check box: Does not apply the color tag when contained within Exchangeable Image File information. EXIF information is typically saved from digital camera settings, and some photographers prefer to disable the wide-gamut tags.

Enable Large Document Format (.psb) check box: Enables Photoshop to recognize Large Document Format files, extending the maximum file dimensions to 300,000 X 300,000 pixels. If this check box is disabled, Photoshop defaults to a limit of 30,000 X 30,000 pixels.

You use this page to tell Photoshop where to look for plug-ins and scratch disks.

Plug-ins are utilities and filters that extend Photoshop's core functionality. The default Photoshop plug-ins folder is located under the main Photoshop directory; install any plug-ins there. However, for sharing with other applications or housekeeping purposes, you might want to use a separate folder for any third-party plug-ins. This page of the Preferences window enables you to specify an additional folder for Photoshop to access.

As Photoshop manipulates files, it temporarily appropriates hard disk space to free up RAM memory. When you work with larger files, it's even more important to have free disk space for the scratch disk. This page of the Preferences box is also the place for you to tell Photoshop which drives to use for the scratch disk.

Preferences Title pop-up menu: Click the arrow to display a list of other pages in the Preferences window; select an option to open that page. Currently it should be set to Plug-Ins & Scratch Disks to view the options discussed here.

Memory & Image Cache

Click the Next button to go to the Memory & Image Cache Preferences window or select Edit, Preferences, Memory & Image Cache to open the Preferences window to the Memory & Image Cache page (in Mac OS X, select Photoshop, Preferences, Memory & Image Cache).
