The night pictures of both my Leaf River and Bushnell are like this. It is my opinion that it is both a function of camera quality and distance. The real close pictures are not as bad. My better camera does not have this problem even at a distance and it does not have an extra large flash.

You could try changing the EV value to a higher value and/or the white balance to horizon, office or old picture but then your daytime pictures would likely suffer. I have not tried this but I may this weekend to see what happens.

In the end I think that the camera quality rules the day when lighting is not just right.
