Just because I am not breaking any laws does not always mean I am welcomed by the crew to shoot candid photos. If I am discovered shooting and they decide they don’t want images getting out, they may go to great measures to prevent me from getting my shots. Some ways a film production might do this is by blocking my view with equipment or vehicles, shining a bright light in my direction, or having a security guard stand in front of my lens with an umbrella. This is why I prefer stealth mode. It also makes for a better candid photo when the star does not know they are being photographed and are just acting naturally. On the days when there are several other Paparazzi photographers all competing for the same shot, there is no reason to hide. Production does their best to block the view of all the photographers or often just allow us to shoot, considering everyone keeps a respectable distance and does not get in the way of filming.
