One of the techniques for creating stunning photos is to use an expensive camera's depth of field capability. That's where the subject is in perfect focus and the background is blurred and out of focus. Now, some of the newer more sophisticated smartphones have a portrait mode that provides a similar capability. If you have an older device or you can't quite get the images to look right with the limited portrait shooting mode, there's an app for that! It's called After Focus and that is exactly what it allows you to do. You just drag your finger over the areas that you want in focus and then the areas that you want out of focus to get your results. It's a really great option because you can add this effect to any image after you take it: http://appm1.com/afterfocus
