Hi Paul and all,
While "standards" are one thing, I'd say there's a more (im)practical
issue at play here.
We say imagery on the dome doesn't look like our monitors. Things
look fine on the desktop; they look like dogmeat when projected.
That's not a "standards" concern, that's a technology concern.
We could adopt all the standards we want, but if the projectors simply
cannot deliver the desired results, it's rather moot. Put another
way, I think no one's really unhappy with the inherent quality of
fulldome movies that are being produced these days. They look fine --
or good enough for now. It's the projectors -- and their shortcomings
in showing those movies -- that are the bane of our existence.
Those shortcomings are what people are trying to over-compensate for.
The obvious place to do that is in hardware, of course, not the
software or show-ware. In other words, mucking with the movies --
i.e., making them look "worse" in order to compensate for a lack in
the projector -- is creating problem B instead of fixing problem A.
But it's quite possible that "problem A" isn't fixable. You can only
push the projector's adjustments so far. If that color saturation
slider is full right or full left, and it's *still* not enough...
well, standards won't help there either.
I'm not saying the adoption of "standards" should be discouraged. But
the current situation can be, umm, discouraging.
