A picture is worth a thousand words. However, a picture with metadata, security features, a color profile, notes, sound recordings, and other information is worth even more than just a picture! Photoshop 7 offers a number of significant features to help you share your digital photos with others whom you choose, in the manner in which you choose, and with valuable information that you want to pass on or keep for yourself. In this technique, we look at how you can view, add, and edit information that can be attached to your digital photos. Plus, we look at how you can share your digital photos in a secure manner by using PDF files.

Photoshop 7 offers several ways to add, edit, or view a variety of information types that can be attached to an image. We look at File Info, the Image Browser, how you can add notes or sound recordings to an image, and we look at some of the options that you have when you save a file. Finally, we take a brief look at some of the possibilities available to you when you save your images in a PDF document.

■ Choose File ^ Open (Ctrl+O) to display the Open dialog box. Double-click the \13 folder to open it and then click the sunset-before.jpg file to select it. Click Open to open the file.

STEP 2: VIEW, ADD, AND EDIT METADATA BY USING FILE INFO

The Digital Still Camera Image File Format Standard, known as EXIF (Exchangeable Image File Format) was created as a standard for sharing information along with digital images. Most new digital cameras write EXIF data into each digital photo file. Important information, such as the date and time the picture was taken, resolution, ISO speed rating, f/stop, compression, and exposure time are generally provided. Some of the newer digital cameras even allow you to store voice annotations to the files according to EXIF specifications.

To learn more about the EXIF data provided by a specific digital camera, read the camera's documentation. If you are interested in learning more about the EXIF specification, visit www.exif.org.

■ Choose File >- File Info to get the File Info dialog box shown in Figure 13.3.You can now add any information that you feel is useful.

■ The Filename, Caption, Credits, Title, and Copyright fields are particularly useful if you are using one of the Web page formats such as Vertical Slide Show 2 when using Web Photo Gallery. If you have values in these fields, you have the option of having these fields be automatically placed on a Web page when Web Photo Gallery creates Web pages — a huge timesaving feature!

■ Click in the Copyright Status box to select Copyrighted Work. Turning this feature on makes the copyright symbol show in some application's title bar to make it easy to be aware that the image is copyrighted.

■ To insert a copyright notice in the Copyright Notice box, press Alt+0169 to make the copyright symbol and then type a year and your name.

■ Click the Section box in the File Info dialog box and select Keywords (Ctrl+2) to get the dialog box shown in Figure 13.4. Many of these keywords can be accessed by third-party image management applications.

■ Click the Section box in the File Info dialog box and select Categories (Ctrl+3) to get the dialog box shown in Figure 13.5.

■ Click the Section box in the File Info dialog box and select Origin (Ctrl+4) to get the dialog box shown in Figure 13.6.

Photoshop 7 supports the image information sharing standards of the Newspaper Association of America (NAA) and the International Press Telecommunications Council (IPTC). This standard includes entries for captions, keywords, categories, credits, and origins. In Windows, you can add file information to files saved in Photoshop, TIFF, JPEG, EPS, and PDF formats. In Mac OS, you can add file information to files in any format.

If you are not a press photographer, you may be asking yourself why you should care about all these standards. The answer may be that you don't and ought not to care! However, you can still put this information storage feature to tremendous use.

■ Click the Section box in the File Info dialog box and select EXIF (Ctrl+5) to get the dialog box shown in Figure 13.7. Scrolling down you can learn all kinds of details about the photo. It was taken with a Canon EOS D30 camera on March 12,2002, fifty seconds after 9:31PM! The ISO speed rating was set to 100. The focal length was 33mm — an odd focal length, so it must have been a zoom lens (which is true as a 28-70mm zoom was used). The aperture was set at f/8.0 and the shutter speed was set to Msth of a second.

■ Click OK to close the File Info dialog box. When you save the file, all the information that you enter is saved in the image file.

STEP 3:VIEWING INFORMATION BY USING THE FILE BROWSER

Besides viewing picture information in the File Info dialog boxes, you can also view EXIF data by using the File Browser.

■ To view the File Browser, choose Window ^ File Browser. It should look similar to the one shown in Figure 13.8. The menu button in the File Browser and the status bar offer you a lot of selectable options for determining what information you show and how it is presented. More EXIF data is shown in the File Browser than in the File Info dialog box. Figure 13.9 shows all of the EXIF data for the sunset image.

STEP 4: ADDING NOTES AND AUDIO ANNOTATIONS

Photoshop 7 offers two valuable features that make it easy to communicate additional non-picture information with others or to just make notes for your own use.

■ To add a note to the image, click the Notes tool (N) in the Tools palette. Click anywhere in the image to create a sticky note.You can now type your comments in this note. These notes can be moved, collapsed, and deleted at any time.

■ If you have a microphone connected to your computer, you can also record a voice annotation by clicking the Notes tool in the Tools palette; wait for the pop-up menu and select the Audio Annotation tool. To make a voice recording, click the image to get the Audio Annotation dialog box. Click the Start button and begin speaking in the microphone. When you are done, click Stop to place an icon in the image indicating there is a voice message that can be played back. Figure 13.10 shows several notes and voice annotations that have been placed on the image.

STEP 5: USING THE SAVE AS AND SAVE COMMANDS

When considering the extras that can be added to a digital image, it would be wrong not to consider Channels, Layers, Annotations, Spot Colors, and ICC Profiles.

■ Choose File >- File Save As to get the Save As dialog box shown in Figure 13.11 .Here you notice a few check boxes that may be checked or unchecked to determine if a certain type of information is to be added to the file after it is saved. Click Cancel to close the dialog box without saving the file.

STEP 6: SAVING A FILE IN A PDF DOCUMENT

Adobe PDF documents have become the de facto standard for sharing documents across most hardware platforms and operating systems. They can be

small compressed files that are easy to e-mail or download from a Web page, or they can be huge files that contain images and all the information needed in a pre-press environment. As it is a feature available to you in Photoshop 7, you ought to take a brief look at how PDF documents can be used.

■ To save a digital image in a PDF document, choose File >- Save As (Shift+Ctrl+S) to get the Save As dialog box. Click in the Format box to get a pop-up menu; click Photoshop PDF .pdf. Click Save to get the PDF Options dialog box shown in Figure 13.12.

Besides having the option of choosing JPEG quality levels, you can also select from a few very useful security options. Click the box next to PDF Security and then click the Security Settings button to get the PDF Security dialog box shown in Figure 13.13. Here you can determine if and how passwords are to be used, plus you have the option of determining if the image may be printed, changed, copied, extracted, or if comments and form fields may be added or changed.

As there are entire books written on the topic of creating and using Adobe PDF documents, I'm going to leave this topic to them. Just be aware that Photoshop 7 allows you to have considerable control over any digital image that you want to share with others.

That concludes this quick tour of the features of Photoshop 7 that allow you to make an image be worth more than a picture! Creative application of these features can be very helpful to you to get more done — quicker and better.
