HDR Camera+ (Android) app for $0.99

Real life scenes often have a wide range of light intensity, which cannot be captured by a camera. In a photo of such a scene, the bright areas look washed out and everything in shadows is pictured as a black spot with no details. The HDR technique allows you to capture details in bright and dark areas and have them merged in a single photo. HDR photography is widely adopted by professional photographers.  You need another decent, but cheap Photo app, check out our entire list.+
