Other things you can do with Photoshop
Admittedly, Photoshop just plain can’t do some things. It won’t make you a good cup of coffee. It can’t press your trousers. It doesn’t vacuum under the couch. It isn’t even a substitute for Zoom, Microsoft Excel, or TurboTax — it just doesn’t do those things.
However, there are a number of things for which Photoshop isn’t designed that you can do in a pinch. If you don’t have InDesign, you can still lay out the pages of a newsletter, magazine, or even a book, one page at a time. If you don’t have Dreamweaver, you can use Photoshop to create a website, one page at a time, sliced and optimized and even with animated GIFs. You can create multipage PDFs and PDF presentations (see Chapter 15). And although you’re probably not going to create the next blockbuster on your laptop with Photoshop, the video editing capabilities can certainly get you through the family reunion or that school project (see Chapter 16).
Viewing Photoshop’s Parts and Processes
In many respects, Photoshop is just another computer program — you launch the program, open files, save files, and quit the program quite normally. Many common functions have common keyboard shortcuts. You enlarge, shrink, minimize, and close windows as you do in other programs.
Reviewing basic computer operations
Chapter 3 looks at Photoshop-specific aspects of working with floating panels, menus and submenus, and tools from the Options bar, but I want to take just a little time to review some fundamental computer concepts.
Launching Photoshop
You can launch Photoshop (start the program) by double-clicking an image file or through the Applications folder (Mac) or the Start menu (Windows). Mac users can drag the Photoshop program icon (the actual program itself, with the .app file extension) to the Dock to make it available for one-click startup. (Chapter 3 shows you the Photoshop interface and how to get around in the program.)
Working with images
Within Photoshop, you work with individual image files. Each image is recorded on the hard drive in a specific file format. Photoshop opens just about any current image file consisting of pixels as well as some file formats that do not. (I discuss file formats in Chapter 2.) Remember that to change a file’s format, you open the file in Photoshop and use the Save As command to create a new file. And, although theoretically not always necessary on the Mac, I suggest that you always include the file extension at the end of the filename. If Photoshop won’t open an image, it might be in a file format that Photoshop can’t read. It cannot, for example, open an Excel spreadsheet or a Microsoft Word document because those aren’t image formats — and Photoshop is, as you know, an image-editing program.
If you have a brand-new digital camera and Photoshop won’t open its Raw images, check your Creative Cloud Manager’s Updates section to see whether a newer version of Camera Raw is available. (But remember that it takes a little time to prepare Camera Raw for new file formats. If you purchase a new camera on its first day of release, you may need to use the software that came with the camera until the next Camera Raw update is released.)
Saving your files
You must use the Save or Save As command to preserve changes to your images. After you save and close an image, some of those changes may be irreversible. When working with an important image, consider these tips:
Work on a copy of the image file. Unless you’re working with a digital photo in the Raw format (discussed in Chapter 6), make a copy of your image file as a backup before changing it in Photoshop. The backup ensures that should something go horribly wrong, you can start over. (You never actually change a Raw photo — Photoshop can’t rewrite the original file — so you’re always, in effect, working on a copy.)
Activate auto recovery. In Photoshop’s Preferences ⇒ File Handling panel, make sure that the Automatically Save Recovery Information Every option is selected and set to an appropriate time interval. If Photoshop crashes while you’re working, when you reopen the program, it will (hopefully) be able to present you with your artwork at the stage when last saved for auto recovery.
Save your work as PSD file, too. Especially if your image has layers, save it in Photoshop’s PSD file format (complete with all the layers) before using Save As to create a final copy in another format. If you don’t save a copy with layers, going back to make one little change can cost hours of work.
If you attempt to close an image or quit Photoshop without saving your work first, you get a gentle reminder asking whether you want to save, close without saving, or cancel the close/quit (as shown in Figure 1-4).
FIGURE 1-4: Photoshop reminds you if you haven’t saved changes to an image.
Keyboard shortcuts
Keyboard shortcuts are customizable in Photoshop (check out Chapter 3), but some of the basic shortcuts are the same as those you use in other programs. You open, copy, paste, save, close, and quit just as you do in Microsoft Word, your email program, and just about any other software. I suggest that you keep these shortcuts unchanged, even if you do some other shortcut customization.
