Continuing with the coverage of the 5D shoot, here’s a greenscreen element we shot a few days ago. The setup was ghetto; a portable screen, filled with wrinkles, in the living room. On any other camera, the wrinkles would have caused problems down the line in compositing, but because we were able to put a 70-200mm lens on the camera, the screen was thrown completely out of focus. That’s not possible to do with prosumer camcorders without a multitude of adapters and accessories, you’d essentially have to put a better lens on the camera somehow. In all of the footage we’ve shot, the huge size of the sensor on the 5D compared to prosumer camcorders really shows in the visual look of the image and the amount of depth of field that is obtainable (take a look at some of the shots in the post below).
Because the screen was thrown out of focus, it was much easier to pull a clean key. The process was also much simpler; there wasn’t a need to pre-blur the green or blue channels to compensate for a 4:2:0 colorspace or other foolishness that accompanies prosumer formats.
I’ve been raving about it quite a bit, but working with this camera is such a breath of fresh air to someone who’s had to work through the godawful limitations of prosumer formats in a demanding visual effects context.
