      If you’re working with a machine that offers Gestures (pinching to zoom, three-finger swipe, and so on) and you like using Gestures, you can use them in Photoshop.

      Preferences ⇒ Interface and Preferences ⇒ Workspace

      The Interface and Workspace panels of the Preferences offers several options of note:

       Appearance: You may find that Photoshop’s “dark interface” is not to your taste. (Try it for a while — it’ll likely grow on you.) You can select from among two lighter (and one even darker) interface appearances.

       Screen Modes: You can easily customize the look of Photoshop’s three screen modes.

       UI Font Size: If you find yourself squinting to read panel names and such, change the UI Font Size to Large and restart Photoshop. If you still have problems reading the screen, reduce the monitor’s resolution. (See Chapter 2 for details.)

       Show Channels in Color: When only one channel is active in the Channels panel, it normally shows a grayscale representation of the image. If you prefer to have the active channel appear in its own color, select this option. Keep in mind, however, that after you get comfortable working with individual channels, the default grayscale is easier to see.

       Show Menu Colors: As I discuss earlier in this chapter, you can assign colors to specific commands in the Photoshop menus. Assigning colors might make it easier for you to quickly spot and select often-used commands. Use this option to disable the color coding without having to deselect each assigned color.

       Auto-Collapse Iconic Panels: If you prefer an uncluttered workplace, here’s a great option for you! When selected, panels in icon mode (click the upper bar of a group of panels) collapse to buttons. To open a panel, click its button. When Auto-Collapse is selected, the selected panel automatically closes when you click elsewhere in Photoshop. If you need to keep a specific panel open while you work (perhaps Histogram or Info), drag it out of its group and away from the edge of the screen, and it will stay open until you close it.

       Auto-Show Hidden Panels: Position the cursor over a collapsed panel and it springs open.

       Open Documents as Tabs: Photoshop, by default, opens each document as a tab across the top of the work area. You click a tab to bring that image to the front. If you find that you’re constantly dragging tabs off to create floating windows, deselect this option in the Preferences. And if you disable tabbed image windows, you’ll likely also want to disable the Enable Floating Document Window Docking option. This prevents image windows from docking as you drag them around onscreen.

      Preferences ⇒ File Handling

      Image previews add a little to the file size, but in most cases, you want to include the preview. On Macs, you have the option of including a file extension or not (or having Photoshop ask you each and every time). Even if you don’t plan on sharing files with a Windows machine, I strongly recommend that you always include the file extension in the filename by selecting the Always option. Likewise, I suggest that you always maximize PSD and PSB file compatibility. This ensures that your Photoshop files can be opened (with as many features intact as possible) in earlier versions of the program and that they’ll function properly with other programs in the Creative Cloud. Maximizing compatibility can be critical if you also work with Adobe’s Lightroom CC.

      Photoshop includes an auto-recovery feature, one that doesn’t compromise the creative process. If, as with some programs, your open file was simply saved to your hard drive at specific intervals, overwriting the original, your artistic experimentation could be limited to that specified time frame. Say, for example, that you tried a specific artistic filter, took an important phone call, and later found out that the program had rewritten the file on your hard drive and that experimental filter has become a permanent part of your artwork. But you decided you don’t like it after all. Bummer! (Or simply Undo, of course.) Rather than take such risks with your creativity, you now have the option to have Photoshop save recovery information, which doesn’t affect the original file in any way, at intervals specified in the Preferences. Or you can disable the feature by deselecting the check box.

      Preferences ⇒ Performance

      The Performance panel contains options related to how Photoshop runs on your computer:

       Memory Usage: Try bumping the memory allocation to 100%. If things seem slower rather than faster, back off the memory allocation to perhaps 85%. In a 64-bit environment, Photoshop can take advantage of all the RAM you can cram (into the computer).

       History States: This field determines how many entries (up to 1,000) appear in the History panel. Storing more history states provides more flexibility, but at a cost: Storing too many history states uses up all your available memory and slows Photoshop to a crawl. Generally speaking, 20 or 30 is a good number. If, however, you do a lot of operations that use what I call “little clicks,” such as painting or dodging/burning with short strokes, that History panel fills quickly. For such operations, a setting of perhaps 50 or even 60 is more appropriate.

       Cache Levels: The image cache stores low-resolution copies of your image to speed onscreen display at various zoom levels. Although this process speeds up screen redraw, the price is accuracy. Unless your video card has trouble driving your monitor at your selected resolution and color depth, you might be better served by Cache Levels: 1. That gives the most accurate picture of your work. (But remember to make critical decisions at 100% zoom, where one image pixel equals one screen pixel.)

       Graphics Processor Settings: This area displays information about your computer’s video card. If your system has the capability, you’ll see a check box for Use Graphics Processor. Using this processor provides smoother, more accurate views at all zoom levels and other enhancements, including the capability to rotate the image onscreen — not rotate the canvas, but rotate just the onscreen image. And that’s too cool for words when painting a complex layer mask!

      Preferences ⇒ Scratch Disks

      

Photoshop’s scratch disks are hard drive space used to support the memory. Use only internal hard drives as scratch disks — never an external drive, a network drive, or removable media! If you have multiple internal hard drives, consider a dedicated partition (perhaps 15–50GB) on the second drive — not the drive on which the operating system is installed. Name the partition Scratch and use it exclusively as a scratch disk for Photoshop (and perhaps Adobe Illustrator). If you have a couple of extra internal drives, each can have a scratch partition. (On a Windows computer, you might see a message warning you that the scratch disk and the Windows paging file, which serves the same basic purpose at the system level, are on the same drive. If you have only one internal hard drive, ignore the message.) To re-order the scratch disks, click the scratch disk in the list and then, instead of dragging, use the arrows keys to the right.

      Preferences ⇒ Cursors
