This is my favorite HDR app. It works very well and blend seamlessly as advertised. However you do have to hold the camera steady for rested on a stable surface to avoid camera shake and movement. As for the fix that I mentioned in my title, began with adjustment does not work with iOS 7 and I am currently using the iPhone 5 S. However the rest of the app works fine and all of the adjustment bars work except for the Gamma. Hopefully this can be fixed soon. Other than this, this is a very nice HDR app that blooms three photos very well. And some high contrast situations it doesnt look as great, but for most applications perfect.
