ProCamera 7

Long the photo app that pros turn to when sprucing up their iPhone shots, the latest update added welcome features and design tweaks like AntiShake stabilization, a 6x full resolution zoom, and a RapidFire burst mode that snags up to 10 shots per second. There's also a smooth video focus with real-time video zoom and 120fps slow-motion capture that is fun (and brings slo-mo to older iPhones). Our favorite though is the Night Camera function for sharp, low-noise night shots with the ability to change shutter speeds up to a second for amazing night shooting. [$2.99; iOS]
