Most everyone knows the historocity of the recent weather events. Huricane Sandy and his wake are big news. The civil athorities are rightly requesting for cooperation in staying out of the way. Genuine photographers (you decide if that what you are) have not only an opportunity, but an obligation to record this event. With the availability of imaging technology aqvailable to virtually anyone who wants it today, photographers can make a huge contribution to history by recording anything that seems worthwhile to record.
Use your head, use your eyes, use your cameras. Be sensible and careful. don't endanger yourself and others. Don't get into peoples faces--especially the civil athorities. Don't invade hurting people's privacy. Be sensitive. But record what you can. I am not saying to not take people, pet, and human-interest photos. But if you are ask not to--don't.
These are the times and events that award-winning photos are born of. If you are there--go for it. Only one bit of advice--take gobs of pix.
