Jason's got his photos of The Gates up, I'm sure the rest of the camera-equipped world will follow.
Albert Maysles talks on WPS1 about the 25+year-long process of making his film about The Gates, The Gates. Maysles is making this film with collaborator Antonio Ferrera for HBO, but he also made other Christo and Jeanne-Claude films over the years. [Actually, a lot of them at the time were just Christo films. I'll let the gender studies art historians figure that one out. Ask Coosje van Bruggen about it, too.]
Maysles has switched to DV lately, and revels in being able to be even less obtrusive and more flexible than 16mm used to let them be.
