Iphone 5 facetime front camera

Hello good day. Am I the only one experiencing the dark side of the front cam during facetime?

I tested facetime on both iphone 4 and iphone 5 but it seems that my iphone 5 is very dark if it is agains the light while the iphone 4 gives its best shot to see the person on the screen. It adjusts the camera itself to make the person see unlike on the iphone 5. Thanks for your help.
