Understanding Exposure Settings

Like all digital cameras, the iPhone and iPad cameras estimate exposure automatically. However, you can use the neat trick described in Chapter 2 to override the camera’s guess about the available light to create special effects. More complex cameras always include an automatic exposure option. On some you can also set the exposure manually, often with the help of a built-in light meter. You can use this feature to correct the camera’s light estimate — for example, if the light is complex and you want to bring out the detail in one part of a scene.
