Filmmakers and amateur photographers going beyond snapshots may soon need permission to take pictures around the city.

The city is considering a new rule that would force groups to obtain a permit and take out insurance before being allowed to film or shoot still photos on city property.

The rule, which was proposed by the Mayor's Office of Film, Television and Broadcasting, would apply to any city property, including sidewalks. It would also apply to any group using a camera for more than half an hour or using a camera on a tripod for more than ten minutes.

It does not apply to handheld devices, and the city says it doesn't expect the new rules to affect tourists and regular photographers, even if they're using tripods.

But the New York Civil Liberties Union says the rules would lead to discrimination and selective enforcement by police.

If the mayor's office decides to implement the rule it would take effect in August.
