Using Fading In Fading out animation you can do that where alpha=0.0 /alpha=1.0

animation code

myimageView.alpha=0.0;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
[myImageView setAlpha:1];
[UIView commitAnimations];

In iOS5 you can access main screen brightness:

[[UIScreen mainScreen] setBrightness:1.0];
//
[[UIScreen mainScreen] setBrightness:0.5];
