Ok so it started to snow and it was night and I have some cool lights in my neighborhood. I thought hmmm... lets see what I can capture. So I set out with my camera and did not really capture anything. I went out with my camera set at 400 iso. If I really wanted to get the snow in the picture should I lower or raise the iso? I was hoping to have the surrounding area very dark but the light shining on the road with snow flakes falling underneath. How can I go about it better? Thanks.
