Well, I personally have problems with all of the items. But picked fog, mist, & rain, because I have been on a few vacations where it has rained or been foggy most of the trip (both film & digital). Prints came out very poor, usually too dark. I know answers is likely bracketing and slowing down then shooting.
Also, My hope was to get a fell for what other member also have problems with and to have a little fun. So far the polling is trending toward Nighttime but all votes for Florida are not in yet.
