Adobe Photoshop CS5 One-on-One

7. Review the metadata. The Metadata panel starts off with the
   metadata placard. Detailed in Figure 1-25, the placard lists
   the most essential information about a photograph in the way
   it might be presented by a digital camera. A blank (--) means
   that the information is missing or isn’t available in a way the
   placard understands. For example, I didn’t use any exposure
   compensation when I shot this image.

Below the placard, you’ll see a few metadata categories that

you can open or close by twirling the ▶ to the left of each one.

Pictured in the elongated Figure 1-26, the categories you are

most likely to use often are as follows:

• File Properties houses the most elemental image specifica-
  tions, such as the name of the file, the date it was last modi-
  fied, the height and width in pixels, and other attributes
  that have been listed in the header of digital images since
  the early years of personal computing.


• IPTC Core comes from the International Press Telecom-
  munications Council, a group in charge of standardizing
  the inclusion of credits and instructions in the field of
  photojournalism. The tiny pencils next to the IPTC items
  indicate that you can edit the metadata, as we shall in Step
  9. The Core part is there only to distinguish this recent up-
  date from the format’s earlier versions.


• Camera Data (EXIF) describes the inception of your pho-
  tograph as witnessed by a digital camera. EXIF stands for
  Exchangeable Image File, supported by virtually every
  digital camera sold today. The EXIF data for this particular
  photograph tells us, among other things, that it was shot
  with my Olympus E-30, I used Auto exposure and white
  balance settings, and the flash did not fire.
