Real High Dynamic Range (HDR) Photo Enhancement on an iPhone? Pro HDR app

HDR (High Dymanic Range) photography is a technique that uses multiple photographs taken using different exposure settings (bracketing) to produce a wide range of light intensity levels. This can help make a photo look real or even super-real (exaggerated reality). Based on comments I’ve seen in the iTunes App Store, most of the HDR apps there seem do no more than increase color saturation and brightness. So, I was intrigued to find one iPhone app that appears to be closing in a on producing HDR-like results on the iPhone.
