Changing Your Photo’s Date and Time

As you’ll discover in upcoming chapters, iPhoto is all about organizing and categorizing your photographs. A big way iPhoto helps you do this is with events. For events to work properly, however, your camera must have the correct time and date settings. If it doesn’t, when you search through your events, you might see photos that you took last week show up chronologically in the past—way behind photos you took years ago.

Change a Single Photo’s Date and Time

  1. Select the photo so a yellow box highlights its edges.
  2. Select Photos, Adjust Date and Time. In the dialog box that appears, you see the photo you have selected as well as the original date and time.

  3. Enter the new date and time in the Adjusted field. In the dialog box, you are shown by how much the original date and time will be changed.
  4. (Optional) Select Modify Original Files if you want to change the date and time to the photo’s original file in your iPhoto Library file. Selecting this check box changes the embedded Exif date data. If you don’t select this check box, the original Exif data stays the same, and the date change affects the photo only while it’s in your iPhoto Library.
  5. Click the Adjust button, and the change is made. The new date and time are reflected in the photo’s Information Pane.

Change Multiple Photos’ Dates and Times

You aren’t limited to changing the date and time of one photo at a time. You can change the date and time for an entire event or a group of photos.

  1. Select the event so a yellow box highlights it. If you are selecting multiple photos, make sure all of the ones you want to change are highlighted.
  2. Select Photos, Adjust Date and Time. In the dialog box that appears, you see the first photo of the event or group of photos you have selected as well as the first photo’s original date and time.

  3. Enter the new date and time in the Adjusted field for the first photo. iPhoto uses this date and time to adjust all the other photos accordingly. So, if you change the first photo’s time by adding 37 minutes to it, all the photos that you have selected to change will have 37 minutes added to their times. In the dialog box, you are shown by how much the original date and time will be changed.
  4. (Optional) Check Modify Original Files if you want to change the date and time to the photos’ original files in your iPhoto Library file. Selecting this check box changes the embedded Exif date data. If you don’t select this check box, the original Exif data stays the same, and the date change affects only the photos while they’re in your iPhoto Library.
  5. Click the Adjust button, and the change is made. The new dates and times are reflected in the photo’s Information Pane.
