What Is EXIF?

Throughout this chapter you'll hear me refer to your photo's EXIF information. What exactly is this? Simply put, Exchangeable Image File information is a file format that records associated information with the photo being shot.

Figure 3–2 shows a close-up of the way EXIF information is displayed in iPhoto's Information pane.

Now some of you might see all the numbers in Figure 3–2 and get a little freaked out. Don't worry! You don't need to know what any of the EXIF information means to be a good photographer or enjoy editing and organizing your photos in iPhoto. Apple just added this EXIF information to iPhoto's Information pane for easy reference for those of us who do like to see our photo's EXIF information.
