Last night, I saw my first movie projected from the Sony 4k
projector. The quality overall was ok, but I have a question. I
noticed that blue colors were quite washed out. All the blue looked
gray to me. I don't know how to judge if this reflected problems with
the projector's color rendition, or was instead an intentional
aesthetic choice for this movie (Away We Go). Or, I guess, this
particular projector's color calibration could be off.
I suppose what I'm wondering is if this is a well-known problem with
these projectors. I tried to search, but found nothing. Thanks. |

Sorry for the somewhat-belated reply ...

We had a Sony CineAlta 4k projector as a temporary installation at The
Astor Theatre in Melbourne, Australia, for the director's-cut release of
"Blade Runner."
There were absolutely no problems with the colour or the dynamic range.
The overall quality was astonishing and far in excess, even on a
60-foot, matte screen, of my expectations.
"Blade Runner" was a 2k scan but it was clearly enhanced by the extra
brightness of the 4k projected image.
My only disappointment was that the native ratio was 1.85:1 which meant
not using the top and bottom of the available area for Panavision. This
has, I gather, since been made less of a problem by the use of a custom
anamorphic lens.
During breaks betwen the shows, we were able to see some 4k scans of a
70mm print. It wasn't as good as properly-projected 70mm film but it was
clear that, eventually, projection will not (or need not) be the
achille's heel of digital presentation.
Whatever else, Sony's CineAlta technology shows what can be done with
digital projection

Do you mean they showed the movie with the image squeezed
verticaly ? Or it was cropped by more than one third ? |

Seems pretty clear to me. As is typical in video, the Panavision image
appears in a "letterbox" format with narrow black bars at the top and
bottom.
With an anamorphic image with a 1.85 or 1.78 frame ratio an anamorphic
squeeze of approximately 1.3 is used in the creation of the master and a
compensating anamorphic lens is used in projection.

Yes Marty. That is what I though because he said they did not have
any anamorphic lens when he saw the movie projected.
It seems to me that it was a very bad job to show the movie this
way. |
