Using Depth of Field Techniques with the iPhone's Camera
The depth of field in your photography can have a dramatic effect on your subjects. A focus distance of four feet or more with the iPhone 3GS/4 means everything to the horizon will be in focus. But a focus distance of 4 to 18 inches can bring some compositional magic to your photos.
