Video improvement with ECT is very much like what you describe between
digital and film. Video with ECT looks a lot more like film.
best film is 70mm. The video equivalent of a direct to disc 45. I've
seen Lawrence, My Fair Lady, Hamlet, and The Hateful Eight, all in
glorious 70mm. Tarantino outdid himself filming The Hateful Eight in
Ultra Panavision 70.
None of these is anything like reality.
Which is the whole point. Reality is vastly overrated, at least when it
comes to art. We are after all immersed in reality 24/7/365. (Well, some
of us, anyway;)
The new theatrical 3d format coming out is 'glasses free'. Apparently the image is 3d from any seating position.
It is also going to be done with a scanning laser technology, for a near infinite contrast range - in some ways.
In the same way that commercial theaters fought back via innovation, when TV was introduced... that entire industry and all of it's connected interests...is doing so again....
