Thanks Joe, I'll give that a shot. In the past, I've been using a polarizing filter on my lens, I do have some ND Grads on order, but they haven't shipped yet. As for ISO, I've been using 100, so I'll try going lower.
What do you think about going to bulb setting, what that just wipe it all out, with light I mean? Also, would you recommend shooting those in A or S mode?
