Exposure Issues

 

My iPhone doesn’t allow me to compensate exposure, and it meters the photo based on where I tap focus from. What do I do if I want greater control?

The fact that the iPhone does not have Exposure Compensation is rather pathetic, considering how good its camera is. But it does allow you a lot of control, though in a twisted way. For instance, long pressing the screen while shooting works like an Auto Exposure Lock. You can use this judiciously to avoid overexposing or underexposing a subject. Also, there are plenty of apps such as Camera+ and ProCamera that give far greater control. Some of these also allow you to separate the focus point from the metering area.
