iLife ’11: Save and Match Faces in iPhoto
4 of 8 in Series: The Essentials of Searching for Photos in iPhoto '11
With your help, iPhoto can save and identify faces in your pictures so that you can browse pictures by faces. No, the face-matching process isn’t as sophisticated as the face-recognition technology you see on television crime dramas, but it’s close to perfect for everyday picture browsing.
When you need to find all pictures of your favorite relative or friend, just click Faces in the Source pane.
Saving a face in iPhoto
First, faces need names: You introduce iPhoto to some faces and give them names. Follow these steps:
Select a picture that has one or more faces that appear often in your library.
You can browse by event, photo, or place, as described in this section, and then select a picture.
Click the Info tool on the right side of the toolbar.
The Info pane appears and the picture you selected is enlarged in the Viewer pane.
Click the down arrow next to Faces to open the Faces information, and click n unnamed in the Faces information.
n is the number of unnamed faces.
Click inside the label to add a name for a face.
(Optional) To add a face, click Add a face in the Faces information, and adjust the face rectangle, and then repeat Step 4.
After you click Add a face in the Faces information, a rectangle appears in the picture. You can then drag the rectangle into position on a face and drag the corners of the rectangle to adjust its size. After adjusting the rectangle, repeat Step 4 (add a name for the face).Open the Faces info to see faces marked with labels.Click a face’s label arrow to see all pictures with that face.All the pictures with that face.
Matching faces in your iPhoto library
To match other pictures in your library with a face and name in the Faces browser, follow these steps:
Select Faces in the Source pane.
A corkboard image fills the Viewer pane with any faces you have already named.
The Viewer pane shows the pictures you identified as having that face.Double-click a named face to see more pictures with that face; click Confirm Additional Faces to confirm.
Click the Confirm Additional Faces button.
This button probably should be named Confirm Additional Pictures — it lets you confirm pictures that contain the same face.
Click a face to confirm it, or Option-click the face to reject it.
This feedback gives iPhoto some information to search more pictures for the face and not include pictures that obviously are incorrect matches.
Click Done when finished confirming and rejecting faces.
After you click Done, iPhoto looks for more pictures that may include the same face. You can continue confirming and rejecting more pictures and click Done each time, and iPhoto continues until it can’t find another match.
