Use TrueHDR to unleash the potential of your iPhone (4 or 3GS), iPod Touch (4G) and create beautiful full-resolution high dynamic range (HDR) pictures!
Have you taken pictures, only to find out that the beautiful clouds were washed out, making the sky look like a white haze? Or how about outdoor pictures where everything in the shade looked like a dark blob with no details? Have you taken photos of scenes that included lights (indoors or outdoors), only to see that you had to compromise with an overly dark or overly bright final image?
The problem with taking only one photo of a scene that has a large range from bright to dark is that you have to choose whether you want to capture the brighter or the darker areas.
With TrueHDR, you can get the best of both worlds - capturing the details of bright and dark areas and then merging them into a single photo.
