I reviewed Pro HDR many years ago when it was among the first High Dynamic Range apps and best of the camera apps for the iPhone. In short order, Apple added HDR capability to its own software, but in general the third-party apps do a better job.
Pro HDR X (US$1.99) is a new app that has evolved from Pro HDR. It has solid roots, and this new app pushes your iPhone camera toward better HDR imaging.
