31 iOS Apps That Unlock the Photographic Power of Your Device

Rookie (free) is perfect for beginners. Use Rookie's built-in camera instead of the default Camera app to access granular controls for white balance, ISO, and shutter speed. There are guides to help you find the perfect composition, too. Once you've snapped a photo, Rookie offers advanced editing tools like color temperature and tint as well as fonts, badges, stickers, and frames.
