Sketch: Cinematography

  • Shutter Efficiency and Temporal Sampling: Talking about how CG camera shutters are not realistic at all. Is he saying shutter or shitter? Reyes implementation examples: his motion blur looks very good. He calls this a "low efficiency shutter" for temporal sampling. He calls it a "tent" filter as opposed to a "box" filter... terrible speaker, not really describing his innovation well at all.
  • A New Camera Calibration Method Taking Blur Effects Into Account: Measuring the width of blur in a checkerboard photograph to find the desired point to perform a standard camera calibration.
  • Cinematized Reality: Visual hulls to reconstruct geometry, stored camera paths to "apply expertise." It was more complicated than I thought it would be: relationships and actions in the vh reconstruction are noted, and using traditional filmmaking language, a database of a director's shot types is accessed and a sequence is assembled. A large amount of information must be entered manually, and a director's "technique" needs to be captured in the database. It seems like a silly project, but it's interesting in the context of a pre-viz tool: how can a director's technique be generalized? How can traditional cinematography concepts be enforced in software?
I'm leaving at this point to head back to The Standard for my shuttle pickup...
