โSummary of Lens Issues
Lens distortion is a complex topic with no easy โmake it go awayโ button possible. Each individual cameraโs distortion is different, and distortion varies with zoom, with focal distance, iris setting, and details of the cameraโs sensor technology. We cannot supply you with lens calibration data to repair your shoot, or the awful- looking shots your client has just given you. You should carefully think through your workflow and understand the impact of lens issues and what they mean for how you track and how you render. Anamorphic lenses have all these problems and more (โanamorphic distance!โ), which is why we have a special guide for them.
While SynthEyes provides the tools to enable you to handle a variety of complex distortion-related tasks, obtaining as much information as possible during a shoot is a good way to reduce costs, including set surveys and even lidar scans if possible.
Without it, analysis will be less accurate and more difficult or even impossible. As always, an ounce of prevention is worth a pound of cure.
