Charles will search to find photos that contain both Jennifer and Brian. He taps the search box and it expands and opens the search mode.
Charles notes that "Tags" is selected as the search mode above the keyboard. This is what he wants, so he begins to type Jennifer and Brian's names. As he types, a popover appears with possible friend matches from Charle's friends list. As he types, search results begin to appear. He dismisses the keyboard to see the search results better.

A compose-email window appears, where Charles types his message. Maybe Donovan knows what's up.
Albums/Friends Page
On this interface, a grid of albums (or friends) is shown. Clicking on a photoset opens it in the same style that the iPad uses for folders on the home screen. Close the photoset by tapping outside of the opened portion.
This interface should be easily learned, because it uses metaphors the user is already familiar with.
It is efficient for browsing through large sets of albums, which each contains a large set of photos. The grid formation allows as many photosets or photos to be displayed as possible. You can quickly open and close a photoset without navigating screens.
Because the user is not creating data, there aren’t many errors they can make. If the user accidentally taps on a photoset or photo that they don’t want to browse, they can quickly go back.
Search
Search is the other main mode of PhotoBook (besides browsing). Switching to search is highly visible. The familiar search field is at the top of every page. Tapping it opens the search field, with three search modes shown above the keyboard.
The three search modes are “Tags”, “Title”, and “Uploader”. They can only search by one term at a time. This is a feature limitation, but makes the interface less complicated and easier to learn.
