Steve, no offense was taken, but I did seem to be in a desperate search for the firmest ground possible, didn't I? Sorry about that. I didn't mean to come off as vigilant. You brought up a hot and current issue. That is why I've actually tried to get some positive acknowlegement from subjects before I shoot, but it isn't always possible or beneficial to some "photographic goal." (and boy does THAT bring up some questions!)(posted 8606 days ago)
