When I was talking to Ken Opprann yesterday he brought some important points up. We were discussing gaining access to make photos, and he spoke to me of how your body language, how you stand how you move, how you wait in certain places etc. can communicate important messages to those around you. How you move or do not move will draw people to you, will create curiousity. When people who live in those worlds people approach you, their curiosity in you might help to gain you access. When they see you in a positive non threatening way, when they view you as an allie trying to tell things with honesty then access may be givin.
