There needs to be some stage setting before getting to the post-play-out conversation of Christie’s monumental effort of presenting Hugo at the IBC’s Monday Big Movie Night. So, before elaboration on the details: Hats off to Christie and hats off to lasers – Great Science, Great Movie, Great Effort, Great Presentation.
There are two important “everybody knows” issues that need eliminating before discussing the Christie effort. The first is to counter the wishful thinking that has morphed into a meme-life of its own. It gets stated by people who should know better and was even in an earlier slide presentation in the same auditorium on the same afternoon of the Hugo presentation.
The meme says: There is a SMPTE/ISO/DCI luminance standard for 2D presentations (48 candelas per square meter, or 14 foot-Lamberts), but the DCI 3D document only speaks to starting the sequence with the left eye, 4:2:2 data streams and one other issue and therefore, since it doesn’t speak to luminance, it therefore allows a de facto standard of 4.5 ft/Lamberts.
That is as insane as saying that since the 3D standard doesn’t speak to issues of following the fire code, EXIT signs don’t need to be illuminated during 3D presentations. [DCI_Stereoscopic_DC_Addendum.pdf]
