If you open the Photos app in iOS 7 and start scrolling through your camera roll, you’ll notice that the background is now white instead of black. That would be okay if the app actually showed all of your images. To do that, you’ll need to tap on the picture first, at which time the background will turn black. Why add this extra step to see your whole shot? The good news is that if you tap on a picture and then start scrolling through, the black background will stay and you’ll see all of your photos.
