It would be a major coup if Europe could establish this as the lowest
level of resolution in such a hierarchy. Just for the record, this is
exactly what we recommended in the SMPTE/IEEE Task Force Report on
Digital Image Architecture. And we suggested that this raster be used
in the US.

Didn't we just go through this discussion recently? It seems like
more of an excuse that a real problem. At least, we know how to avoid
the problem. Given the fact that there will be MANY additional costs
for HD production, using appropriate lighting does not seem like much
of a stretch.
