10. Enable automatic HDR (iPhone 5s): Back in 2010, iOS 4.1 added the High Dynamic Range (HDR) feature to its Camera app, which allowed you to take a photo of a subject with both sharp light and deep shadow and have it render as evenly lit. But HDR took longer to shoot than the average image, which for most people meant manually turning it on whenever you wanted to capture that perfect sunset.
With iOS 7 and the iPhone 5s, however, you can turn on automatic HDR mode: In normal light, your iPhone will shoot a regular photo; in situations with multiple light patterns, however, your device will automatically recognize that an HDR photo might be best and attempt to capture that, instead. (As always, the iPhone always takes two photosthe untouched one and the HDR version; you can save both to your Camera Roll if you wish by going to Settings > Photos & Camera > Keep Normal Photo.)
11. Put permanent filters on your camera: Both the iPhone and iPad offer front and back hardware cameras, and on the software side, fun filters for Photo and Square modes to make your pictures more interesting.
If you like having a specific filter on images, you can set either Square or Photo mode to always launch with the image manipulation of your choice. Personally, I have iOS 7's Square mode set to the Noir filter, as I like Apple's black and white correction more than, say, Instagram's.
To set the filter, all you have to do is tap the Filter button in the Camera app while in the mode of your choice. Switch to another mode and you'll once again have a clean slate, but return to your original mode and your filter of choice remains.
12. Share your Photo Stream with others (and let them add images, too): When Shared Photo Streams first launched with iOS 6, they let you share groups of images with any of your friends for liking and comments, but your buddies couldn't add images or video of their own.
iOS 7 has changed all that, letting you open up your Shared Photo Streams to anyone you deem fit for posting. Now, when you create a shared stream, viewing it presents you with two tabs: Photos and People. Tap the People section to access your stream's settings; there, you can turn on or off the Subscribers Can Post toggle. (You can also choose to create a public website, add or delete friends to your stream, and show notifications for the stream.)
13. Use iMovie to create slo-mo clips: iPhone 5s owners can make slow-motion clips to their heart's content thanks to iOS 7's 120FPS slo-mo mode in the Camera app. But older iPhone owners can get in on some of that fun, too — they just need to download iMovie.
