I would dearly appreciate any information leading to improving the quality of my "night pictures" from my DC-2BU Leaf River game cam.

The day pictures are fine---color, clarity resolution, image etc.
However--my night (dark pictures) at the same distance with the flash are all very "cloudy, almost as if the picture is behind a cloud of smoke".

Can anyone assist me with my settings in order to improve the quality of these pictures.

I'll ask NUBO to post one of my pictures here so you could see what I'm talking about. Unfortunately I'm unable at the moment to post my own pictures, I'll ask John for his assistance with this.
Thanks in advance for any help with this problem.
