Now let's take a look at how to view and edit 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 you can shoot photos directly with your built-in camera as we saw in a previous movie in this chapter. You can also save photos you received via email on your device or by saving them from 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're stored on your device. All of your photos are found by tapping Photos. Initially, your photos are displayed by albums. The first item is the Camera Roll.
This album contains all the photos you've shot with your iPhone's camera or that you've saved from email messages or web pages. Basically, the Camera Roll stores all the images that were created or stored from your device and that didn't arrive here by syncing with your computer. If you've never synced photos with your computer, your Camera Roll will be the only album you 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 the photo library, and again, these albums are copied over from your computer when you synced.
So, to view the photos in any of your albums, just tap an album. To view a photo at full size, tap it. Now I currently have my phone in Portrait orientation and this is a Landscape orientation photo. So, I have a lot of unused space above and below it. To view the photo at a larger size, I just rotate my phone. The buttons and controls 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 a photo, you can zoom in on it either by double-tapping it to zoom and then double-tapping to zoom out again, or you can pinch out and pinch in. Now when you're zoomed in, you can drag the photo around to look at different areas of it. But note that when you're zoomed in on a photo, you can't flick to the next or previous photos as easily as when you're zoomed all the way out. You either have to flick harder or just drag the image to the side to reveal the next image, and you can see the next image appears at its default size and not zoomed in. Also notice at the very bottom of the screen when you can see the controls is a Play button.
This is for playing your photos as an automatic slideshow. On this screen, you can choose what kind of transition effect you'd like to see between photos. You can see I have five choices. I'll leave Dissolve selected. You can also choose to play any music you have stored on your device as the soundtrack for your slideshow. I'll leave Music off for now and tap Start Slideshow. This is a nice way to show your photos to someone else without having to flick through them all manually. Notice the nice cross-dissolve 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 by tapping a picture, 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.
You can 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 photos for the moment, and now I'll go to Settings>Photos & Camera. And here under Slideshow, you can determine how long you want each photo to be on 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 [00:03:2548] view most photos, especially if you have a lot of photos in your album to get through. The other two options here 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 are displaying photos in sort of a Kiosk mode setting. And Shuffle displays the photos in your album in a random order. I'll leave them both off for now. All right. Let's go back to our Photo Library. To return to your album, tap the screen and tap the button in the upper left-hand corner.
Now if you've ever synced your iPhone or iPod touch with a Mac, you may also see categories like Events, or Faces 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. If you see the Faces Tab, your photos are organized based on the people who appear in them. This is possible because of iPhoto and its face recognition capabilities. Now if you sync your iPhone or iPod touch 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 of where they were shot.
If you've taken 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 geo-tagged your photos in iPhoto, they will show up here under Places on your iPhone as well. So, the last thing I want to show you here is that you can also perform basic edits to your photos directly here in the Photos app. Start by finding a photo you want to edit, and select it. Then tap the Edit button. That gives you a handful of tools at the bottom of the screen.
The first tool is the Rotate button. This is useful if you have a photo that's rotated to the wrong orientation. Sometimes when you take pictures with your iPhone, the device doesn't register the rotation properly, and you end up with a sideways picture. All you have to do here is tap the Rotate button until the picture is right side up. Next is the Enhance button. This is an automatic enhancement feature that has no settings. It simply examines your photo and does its best to adjust the brightness, contrast, exposure, and other settings to make the photo pop a little bit more. Just tap the Enhance button, and in a second, you should see a change to your image.
You can tap the Enhance button again to remove the effect or to toggle between the original and enhanced version. If you like what you see, tap Save. Now if you are editing an image you shot with your device, when you tap Save, you're going to save over your original image. So, make sure the edits you've made are really what you want. But if you're editing a photo in an album you imported from your computer, you'll be able to save a copy of the image to your camera roll. That way, you won't change the original photo and you can always go back to it if you want. But just be aware that saving an edited photo from your camera roll changes the original image. Let's open up another photo.
The next editing tool is the Redeye tool. This is useful for getting rid of those red demon eyes that are often caused by using the flash when shooting photos in dark environments. Start by zooming in on the eyes you want to correct. Then tap the Redeye tool. And as you can see here, it just tells me to tap each red eye. And just like that, they'll be automatically corrected. You can also tap the eyes again to undo the effect if the effect doesn't look right to you, or if you just want to have this weird one fixed eye and one nonfixed eye look. Also, the Enhance button will automatically remove redeye as part of its enhancements.
I'll tap Apply. The last tool is the Crop tool, and as its name implies, this is for cropping down your photos. Selecting it puts a grid on your photo and you can drag any corner to resize the grid to any proportion. The area of the photo inside the grid is the area that will remain once you finish your crop. You also have the option of tapping Constrain to keep your grid locked into specific proportions. Maybe in this case, I want to make my photo a perfect square. So, I just got the Crop Grid to the approximate size I wanted and then I constrained it by making it a square.
When I'm happy with the way it looks, I tap Crop, and again I can tap Save. So, all of the changes I performed to this image were only saved once I tapped the Save button. I could always undo them or cancel my changes before saving. That's how to work with the photos in the Photo App of your iPhone or iPod touch.
