Tonight is my Towns Christmas parade. I think I can get onto the judges stand to take pictures. I will be using a D2X with either a Nikon 35-70 2.8 or a Sigma 18-50 2.8. Where do you think I'll need to have the iso set to get a some good shots. I'll need pretty good depth of field and enough shutter speed to stop the motion. The streets are fairly well lit and of course there are a lot of Christmas lights.
