I need an application runs on iPhone to help in watching dawn: - The user will set the start time of the application to a specific time. and set the period in minutes. (usually it will be around 30 minutes before the dawn and period is 60 minutes) - The user will put the iPhone to face the direction of sunrise position at horizon - When the start time occur, the application will start having series of pictures every minute for the specified period of time (or it can record a clip for that period then take snapshots from the clip every minute( - The application will measure the "light" in every picture and draw a graph (time of the picture in minutes VS measurement of light in the picture). --- The core work is how to measure the "light" in the picture. This needs a research in scientific sources. * Note: If there is a light exposure control in iPhone camera, it needs to be disabled in order prevent it from effecting the accuracy of the results.

Greetings from Portugal! I am a highly experienced C++ programmer with more than 20 years in the field. I have worked extensively with 3d graphics, audio, game, educational, and database oriented software, with clients including Microsoft, Turner Broadcasting, and Dun & Bradstreet. Your project is quite interesting, and straightforward enough. In terms of feasibility, the only issue is indeed, how to measure how much light is in the picture. The simple approach is to add all the values of each pixel and divide by the total number of pixels. This gives you an average luminosity in the image. This does not however, compensate for "dark objects" such as a mountain or a building. I think the thing to do would be to detect edges in the image, and exclude portions of the image from the luminosity average. I love do this kind of research! Please check out my profile, and also visit my website to see some of the more speculative and creative projects I have worked on: [login to view URL] I look forward to hearing from you, please do not hesitate to contact me if you have any questions.
