When needed, the Editor can display information about the basic characteristics of an imageits file type, resolution, size, and data specific to the conditions under which it was taken. To display this metadata (so-called because it's stored at the top of the image file) for any image open in the Editor, select File, File Info from the menu bar. A dialog box opens, loaded with information about the current image.
The File Info dialog box contains lots of information about your image.
On the left, you'll find a list of categories of information stored within the image file. Click a category to display its page of information. For example, click the Camera Data 1 category to find out what the flash setting was when you took this photograph. Some metadata can be entered by you, simply by clicking inside any of the white boxes. For example, you might enter your name under Author or type in a Copyright Notice. Metadata you can view but not change is shown in gray. This kind of metadata is typically EXIF data that your camera recorded when the image was taken, such as shutter speed and f-stop.
You can also change some of this metadata through the Organizer. For example, if you click the Description category on the left, you'll see the text caption you entered in the Organizer (shown here as the Description) and any tags or collection markers you attached to the image (shown here as Keywords).The metadata you enter manually is stored in the alpha channel of the image. Metadata you enter through this dialog box is permanently saved only if you store the image in PSD, TIFF, PNG, GIF, or JPEG format. At the bottom of the Description page, you'll find basic information about the image, such as the file date, modified date, and file type.
You can add a copyright notice on the Description page by changing the Copyright Status drop-down list to Copyrighted, and typing your copyright text in the Copyright Notice text box. You can add your Web page address in the Copyright Info URL box. Note, however, that copyright data such as this is of limited use because anyone with a program capable of reading image metadata can change or remove it. Better to protect your images with a copyright that can't be removedsee 191 Add Copyright Information for help.
As I mentioned earlier, metadata your digital camera recorded when the shot was takensuch as the camera type, date the photo was taken, and shot conditions such as f-stop, shutter speed, and focal lengthcan be found on the Camera Data 1 and Camera Data 2 pages in the File Info dialog box. Some of this data can be used by an EXIF-compatible printer to print your photo more accurately, with better color and brightness matching. To make sure that you don't lose this valuable EXIF data, save your digital camera file using an EXIF-compatible program (Photoshop Elements just happens to be one), in an EXIF-compatible format (Photoshop PSD or JPEG). See 105 Ensure That What You See Is What You Get for more information.
Also on the Camera Data 2 page, you'll find the image's current size in pixels, resolution, and ICC color profile (listed here as Color Source).
In the Organizer, the Properties pane can provide you with further information about the currently selected image. To display the Properties pane, click the Show or Hide Properties button on the Options bar, or choose Window, Properties. Although the Properties pane also displays EXIF data, it includes other information that you won't find in the File Info dialog box. In the Properties pane, you'll find information about where the image is stored, its file date, text caption, audio caption, and any notes you attached on the General tab. Markers you might have attached to an image are listed on the Tags tab. The file date, modified date, import date and related information can be found on the History tab, and EXIF and other metadata is located on the Metadata tab. To display a condensed version of the metadata, select the Brief option; to display all the metadata, select the Complete option instead.
The Properties pane enables you to access image information from within the Organizer.
