In iPhone and iPod Touch iOS 4 Essential Training, Garrick Chow provides in-depth instruction on all aspects of the Apple iPhone and iPod Touch (OS 4.0): making calls, emailing, browsing the web, managing time, getting around town, taking notes, taking photos, and listening to music. This live-action course includes hands-on demonstrations of how to accurately type and efficiently use finger gestures, and includes tips for setting up the iPhone and iPod Touch so they behave as expected. An extensive section on troubleshooting helps when the occasional glitches happen.
Now, let's take a look at how to view the photos stored on your iPhone or iPod touch. Again, photos can be moved to your device by syncing it through iTunes, which we looked at how to do in Chapter 3. Or if you have an iPhone, you can shoot photos directly with your built-in camera, as we saw in a previous movie, and you can also save photos you received via e-mail on your device, or by saving them for web pages, as we'll see in later chapters. But in this movie, we're going to look at how to view your photos once they've been stored on your device. All of your photos are found by tapping Photos. Initially, your photos are displayed by Albums.
On an iPhone, the first item is the Camera Roll. This album contains all the photos you've shot with your iPhone's camera. If you're using an iPod touch, the first album is called Saved Photos, which contains all the photos you've saved from e-mails or web pages. Basically the iPhone's Camera Roll and the iPod touch's Saved Photos albums store all the images that were created or stored from your device, and didn't arrive here by syncing with your computer. If you've never synced your photos with your computer, your Camera Roll will be the only album you'll find here. If you have synced with your computer though, you'll find an album called Photo Library.
This contains all the photos you've copied over from your computer. These are the photos found in any of the individual albums you see below Photo Library in the main album list. And again, these are albums you copied over from your computer when you synced. So, to view the photos in any of your albums, just tap in Album. This displays all the photos from the album as thumbnails. Here, you can scroll through your images. To view a photo at full size, tap it. Now, I currently have my phone in portrait orientation, and this is a landscape photo.
So, I have a lot of unused space above and below it. To view the photo at fullscreen, I just rotate my iPhone. The buttons and controls that appear at the top and bottom of the screen will disappear on their own after about five seconds, but you can also single-tap the screen to bring them back, or tap again to hide them once more. Single-taps show and hide the controls when you're viewing photos. You can browse through the photos in this album by flicking left and right. To get a better look at the photo, you can zoom in on it, either by double-tapping it to zoom in and then double-tapping to zoom out again, or by pinching out and in.
Now, while you're zoomed in, you can drag the photo around to look at different areas of it. Note that when you're zoomed in on a photo, you can't flick to the next or previous photos very easily. You either need to flick harder or drag the image to the side to reveal the next image, which appears at its default size and not zoomed in. Of course, you can always use the Forward and Back buttons to go from photo to photo too, regardless of whether you're zoomed in or not. Again, just tap once to reveal the buttons and use them to navigate through your photos. Also, notice at the very bottom of the screen is a Play button.
This is for playing your photos as an automatic slideshow. This is a nice way to show your photos to someone else, without having to flick through them all manually. Notice that the nice cross-dissolved transition with each photo fading out as the other one fades in. During the slideshow, you can rotate the phone as necessary to accommodate portrait and landscape photos, and you can also stop the slideshow on a picture by tapping, which you might want to do to let your friend take a longer look at it, or if you want to explain how or where the photo was shot. Resume the slideshow by tapping the Play button again.
Now, you can also control how the slideshow plays your photos, to some extent. I'm going to press the Home button to close the photos for a moment, and now I'll go to Settings > Photos. Here, you can determine how long you want each photo to be on the screen. You can select 2, 3, 5, 10, or 20 seconds. I would generally stick with 2 or 3 seconds for each photo. It doesn't sound like a lot, but it's actually a decent amount of time to view most photos, especially if you have a lot of photos in your album to get through.
Next, you can choose the kind of transition you want to have occur between the photos. We saw the default Dissolve transition, which fades one photo out as the other fades in. You can also choose from Cube, Ripple, Wipe Across and Wipe Down. Each of these are more animated than the Dissolve transition. I'll choose Cube, and we'll see that in action in a moment. Of course, you can also come in here on your own and check out other transitions, if you like. The last two options are Repeat and Shuffle, which are simple On and Off choices. When on, Repeat starts your slideshow over from the beginning when it reaches the end, which might be useful if you have your iPhone or iPod touch connected to a TV, where you're displaying photos in sort of a Kiosk mode setting and Shuffle displays the photos in your album in a random order.
I'll leave both of these off for now. Okay, let's go back to the Photo Library, and I'll tap the Play button, and there's the Cube Transition Effect, which is a little more visually active than the dissolve transition, maybe distractingly so. It's up to your own preferences to select a transition you like. To return to your album, tap the screen and then tap the button in the upper left-hand corner. Now, lastly, if you've synced your iPhone or iPod touch with a Mac, you may also see the Events and Faces categories at the bottom of the screen.
Events are based on the events created in iPhoto, in which photos are organized into the dates and times during which they were shot. Under Faces, your photos are organized based on the people who appear in them. This again, is possible because of iPhoto, and its face-recognition capabilities. Now, if you sync your iPhone or iPod with a PC, you won't have the Events or Faces categories, but you might have Places. Places, allows you to view your photos based on the GPS location data where they were shot. If you've taken any photos with your iPhone's built-in camera and you have location services turned on, your photos are tagged with GPS data and will appear here.
Tapping a pin lets you see all the photos that were taken at that location. Also, if you sync with a Mac and have geotagged your photos in iPhoto, they'll show up under Places on your iPhone as well. And that's how you view the photos in your Photo Library on your iPhone or iPod touch.
