Write an iPhone application (using camera and simple algorithm available online)

Deadline: 15 - 20 May The application would be basically representing HDR camera. Since camera in our iPhones is not HDR (and it imitates HDR disappointingly), I need an application that will do it better. Basically, when a user opens application, camera will show up, and upon pressing a button for capture it will take multiple pictures with different exposures of same scene and use algorithm to fuse them all into a single HDR image. The only thing needed is that the result is better than iPhone's offer. Time needed for image acquisition or processing is not a problem, nor the space of application (some reasonable is expected). On the Internet, there are multiple algorithms for merging multiple images with different exposures into one high dynamic range image. Note: This application will not be used in commercial purposes nor it will be published on Apple Store, so after June-July 2016 You are free to publish it and copyright is Yours. What I need is just the source code, to study it and see how does it work since I am doing a research on this topic, and I guarantee that it will not be misused.
