What really makes a photo look professional is the depth and different layers, or in other words, the "background blur". When the background is out of focus, the foreground appears more crisp. Even an iPhone camera can do this. It takes a bit of work, but eventually if you keep tapping the screen and refocusing you will get the perfect image. And don't worry, you'll notice it, it will be obvious how clear and high quality it is. The perfect focus depth completely enhances a photo. Here are some we took with only an iPhone. See how every one has a clear, crisp foreground object and a nice "background blur."
