Bridal---tag along

I am sure shot at a different angle it would be better, but where you were the second shooter you may not have had a lot of control.  It is over exposed.  It would have been okay if the surrounding wall was darker, you could have had more detail in the dress.  In a situation like this bracket your shots.  Take three different exposures since you won't be able to tell on the back of the camera what the outcome will really be.  You probably did want it fairly bright, but not quite as overexposed as what you got.
