Maybe you're not the most accurate when it comes to snapping photos. Maybe you're always just a little too late, or a little too early. Congratulation on being a human like the rest of us. Window's Research new camera application—BLINK—can give you a hand with that (the picture-taking) on Windows Phone 8. How? The shotgun approach.
Much like Nokia's Smart Group Shot, BLINK controls for lack of quality with an excess of quantity. Unlike Nokia's solution, you can get it on any Windows Phone. As soon as you go to take a "shot" with BLINK, it'll go ahead and capture nearly a dozen, after which you can scroll through the results and pick out your favorite. Once you've done that, you can get rid of all the trash, or hang onto it in case you change you mind later, or want to print a flip-book or something.
Once installed, BLINK will show up as a lens on WP8 Phone, and if it seems up your alley, you can download it right now, from the Windows Phone 8 store for free.
