Sams Teach Yourself Mac OS X Digital Media All In One - page 204


Summary

You are starting to learn your way around the Photoshop Elements screen, and you have learned how to open a new page. You've looked at the toolbox and the palettes, at least a little bit. You know about the Shortcuts bar and the Options bar. Most important, you know where to look for help.


Chapter 22. Starting, Saving, and Printing Your Work

In the previous chapter, you learned a couple of ways to open a blank image file. (I sneaked it in ahead of this chapter so you could try out some tools.)


Starting a New Image File

Let's take another quick look at the New dialog box before we move on. Here it is again, in Figure 22.1, just to refresh your memory.

Figure 22.1. The New dialog box is used to create a new image file.

Starting at the top, you have the option of immediately naming your image, or leaving it untitled until you save it. Because I am almost always in a hurry, I skip that step and immediately consider page size. In this version of Elements and in the recent release of Photoshop 7, this dialog box has been modified to add a pop-up menu of possible page sizes, shown in Figure 22.2. The default is horizontal, 7x5 inches.

Figure 22.2. Most of the standard American and European page dimensions are included.

Choose a page size that's appropriate for what you want to do, remembering that screen formats are horizontal, while magazine covers and illustrations are more likely to be vertical. Landscapes and portraits dictate different orientations because of the shape of the subject.

If you have something on the clipboard that's waiting to be pasted into your new image, the dialog box will open with that item's dimensions in place of whatever other numbers might be there. You can still override it and choose a larger size, if you want.

Resolution is a tricky issue that we'll discuss in depth in the section, "Adjusting Resolution." Meanwhile, if your art project is to be viewed on the screen, perhaps as part of a PowerPoint slideshow or on the Web, or if you are just playing, as we are now, use 72 pixels/inch as the resolution. (By the way, we'll be taking a close look at options for online graphics toward the end of this chapter.)

You have only three choices for Mode in this dialog box. If you're working in color, you must choose RGB Color as the mode. Grayscale lacks color, and Bitmap means simply black or white pixels, with no grays at all. If you want to use Indexed Color mode, you'll need to select that option from the Image, Mode menu after creating the file using RGB Color or Grayscale.

The Contents options refer to what appears on the first layer of the image when it's created for you. White is the usual choice. Background applies whatever color is the current background color in the toolbox. (By default, it's white.) Transparent backgrounds are indicated by a sort of gray and white checkerboard effect. (You can change its color in the Preferences.) Transparent backgrounds are extremely useful when you are creating Web graphics.

When you're ready, click OK or just press Return to open the new image.


Browsing for a File

Most of the time, though, you won't be starting with a blank image. Instead, you'll have a photo that you want to work with. If you know where it is, you can press Command-O, click on the Open icon, double-click the file, or do whatever you generally do to open a file. If you don't know where on the hard drive your picture is, you'll turn to the File Browser. Open the File Browser by clicking its tab in the palette well, by choosing it from the File menu or the Windows menu, or by typing Shift-Command-O.

You can select the thumbnail size from the More menu or by clicking the View By button. The File Browser can also show you the file hierarchy and the creation data or camera file info, as well as a larger thumbnail of a selected image, as in Figure 22.3. Normally, all information about a file is displayed in the info window; to display only camera/scanner information, select EXIF from the menu on the lower right. As I mentioned the previous chapter, you can change the sort order using the options on the Sort By menu.

Figure 22.3. The info window includes creation date, camera used, and so on.

Use the top pop-up menu to locate the disk and folder you think the file is on, and just start scrolling through the folder list on the left until you find it. Drag it into an Elements window or double-click it, and it will open on its own.

To rotate the selected image 90 degrees to the right, click the Rotate button. To delete the file from your computer, click the Delete File button.

Task: Browsing and Opening an Image

Time for a little practice. The following steps will walk you through the process of browsing for some picture files on your hard drive:

  1. Go to the palette well and locate the File Browser tab. Click it once. If you don't see the File Browser in the palette well, choose Window, File Browser to open it.

  2. After the window opens, use the scrollbar to review what's on the desktop.

  3. Use the pop-up menu at the top of the browser to navigate to a different hard disk, disk partition, or other external storage device. Again, scroll through to see what's there.

    Remember, you can customize iPhoto so that images in your photo library open directly in another photo editor, such as Photoshop Elements. Simply open the iPhoto preferences and change the Double-click setting to Open in Other. In the file browser that appears, navigate Photoshop Elements and choose it. Now, when you double-click an image in your iPhoto Library, Elements will start up and your image will be available for editing.


  4. The top-left browser window shows the file hierarchy. Scroll down until you locate the folder where a photo you'd like to select lives. Then click the file when it appears in the list on the right. It should be highlighted.

  5. Read through the image information in the bottom pane. If it is a digital photo that you've shot and saved to the computer, you can find out a lot about it. What was your shutter speed? Did you use a flash? If you scanned it in, when did you do so? What's the resolution?

  6. Double-click the file to open it, or drag it into the Elements window.

  7. Notice that the File Browser remains open. If you like, explore your hard drive(s) and locate more pictures you want to come back to and work on later. When you're done, close the File Browser.
