ISO sets the amount of light-sensitivity for the camera sensor. The higher the ISO, the higher the amplification factor of the sensor. The good part of amplifying light is that the photo obviously gets brighter. Having a working knowledge of ISO will help you make wise shooting choices so you can take the best photos for any given situation. Since the aperture on the iPhone camera is fixed, you really only have two variables to work with in controlling exposure — shutter speed and ISO.
When freezing or blurring of the subject is most important, then I make sure I get the optimum shutter speed.

Do not let this discourage you. By making sure that the dynamic range of the scene 8 stops does not exceed the dynamic range of the sensor 8 stops and blowing out highlights or losing shadow detail, you can create photos that will trick people into thinking you own a fancy DSLR.
