For the The Social Network, Fincher re-teamed with Jeff Cronenweth, do we need to mention, son of DoP Jordan Cronenweth, responsible for Blade Runner photography. His father also worked two weeks into production of Alien3 before being replaced, and died in 1996.
Jeff Cronenweth first worked as camera operator of Se7en and second unit DoP of The Game, before being in charge of Fight Club. He also did an amazing job for one of my favourite Fincher's video A Perfect Circle's Judith. So for anyone familiar with Fight Club , The Social Network photography is pretty much familiar ground.
In the American Cinematographer October issue, Fincher talks a lot about the use of the Red One camera. It's pretty technical but proves very insightful for any Fincher fans!
[David] likes symmetry — balanced compositions, strong lines, level frames, zero keystone effects. He favors [dolly] track and avoids cranes as much as possible. I believe there is only one handheld shot in the entire movie. David was so clear on what he wanted visually that camera placements and focal-length choices were easy to make.
