iPhone camera with Flash options

iPhone + photography, or more affectionately referred to as iPhoneography, continues to dazzle. The iPhone 4 and later versions include standard flash options in the resident camera app.
The flash controls, located in the top left corner, are:
Auto – allows the camera to decide whether flash is necessary
On – forces flash for the photo capture
Off – no flash is activated
In the photos below, using natural light on the left gives a soft look but the backlight caused a wash out in the top portion of the photo. The photo on the right with flash activated balanced the light more effectively on the primary subject.
The decision to use flash while making photos of still life may be more of an artistic nature. Choosing flash while making photos of people may be more by necessity. However, be aware that activating the flash delays the capture timing so a tripod may be necessary to get the effect you want.
