The document discusses how to integrate camera and photo apps with Windows Phone 8. It covers how apps can be selected from the Photos hub or camera viewfinder, and how they can access photos via shared picker or rich media extensions. It also demonstrates the Imaging SDK for applying filters and editing photos natively, and how to support higher resolutions on devices like the Lumia 1020.
