A new Apple patent describes a system which allows an iOS device remotely controls multiple secondary devices. The patent called as an “Illumination system” allows Apple’s mobile products to function as remotely-controlled lights for a primary camera. It should be noted that such a primary unit can be either a dedicated camera or a handset with image capture capabilities, while the secondary device can be any other device. The principle it works is the following: the primary unit sets up a connection with the one or more secondary devices. After taking a test image to determine the illumination requirements of a scene, it provides the secondary devices with a signal.
“As one example, a display associated with (or incorporated into) a secondary device may display text instructing a person holding that device to move in a particular direction, for a particular distance, to angle or move the device in a certain manner, and so forth,»-the patent stated.
That means that the primary unit can send instructions remorely to the person holding the secondary device. By the way, with a graphical interface a user can preview a test shot and offer control over the secondary devices acting as slave flashes. It’s also possible for the primary device to display scene options which automatically change slave units’ flash fire intensity or send instructions for repositioning.

It was not the one person who’s responsible for the idea connecting multiple iOS devices, so the patent can be supposed to be “social camera flash” system. It also should be mentioned that Apple’s remote flash patent application was first filed in November 2011.
