iphone - Is there a way of adjusting the screen brightness programmatically?

Question

I have an iPhone app for photographic purposes (kind of a lightbox). This app needs as much brightness as possible. Is there a way to change the screen brightness programmatically, and then restore it back some time later?

Answer 1

Edit: iOS 5 now includes a screen brightness API.

[[UIScreen mainScreen] setBrightness:0.5];

Previous answer:

No, this capability is not exposed via public APIS.

Edit: Note that a future possible iOS release may or may not have screen brightness on the multitasking bar on one particular iDevice.
