A minor firmware change released for the Canon 5D during the Iron Man 2 shoot allowed cinematographer Matthew Libatique to use it for some of the film’s action sequences.
In a press release which you can read in full here, Libatique explains how a bunch of 5Ds were used to film background plates and crash cam shots during the film’s plot-setting Monaco Grand Prix scenes.
He says:
“The new manual exposure firmware introduced during the shoot enabled us to expose 5D Mark II imagery more similarly to the film we were shooting. That was the sealer for us … There is no other camera that can really get into some of the tight spots that the Canon 5D can, and with the ease that it can. We got extra angles in spots that we wouldn’t have been able to get in 35mm without a lot more effort.”
A series of 5D cameras were mounted alongside the race track to capture footage of passing cars; more were mounted on the cars themselves. One of the movie’s finest action shots, of hero Tony Stark’s car flying up in the air after it’s been attacked by bad guy Ivan Vanko, was captured by a 5D mounted on the car itself, inside a padded impact-protection box.
