As part of Apple's massive iOS 7 update, the buit-in Camera and Photos apps have received huge changes. When you're shooting, you can pick a square, Instagram-style aspect ratio and add filters. Once you're done shooting, the Photos app now includes "moments," an automatic organization structure that puts the photos in your camera roll into logical events — much like the Mac version of iPhoto. As for sharing, Airdrop is built right in, and iCloud photo sharing has been improved as well. You can share your photos into other photo streams, and other people can share into your photo streams. Of course, the entire interface has been redesigned, as well, to match iOS 7's radical new visual style.
