Thanks for all the constructive and informative feedback on aspect ratio “religion”, various masking options (both external and internal to projector with JVC's installation modes -on topic!
Sorry my poor worded post on “CIW” sparked so much discussion
, but I learned something, and that's always a good thing. While not “Orthodox” in my beliefs, I am actually a bit closer than you think in my beliefs
as a “layperson” in the aspect ratio religion. Your feedback admittedly did strengthen my faith
I was aware of size and seating distance recommendations when I bought current 16:9. At 9-10 feet viewing distance of 135” 16:9 masked down to ScopE ==> 49” height is approaching min 2 times height seating distance recommendations for ScopE I wanted. (brightness and 7.4.2 speaker placement further constrained size and seating choice)
Acoustic Frontiers has a good pic with various organizations recommendations on seating distance all on same pic. Assume you “Aspect Ratio Priests, Imams, Rabbis, Gurus etc” have already seen it ;-)
I fully understand recommendations take into consideration both resolution, and vertical viewing comfort on typically framed content
. I actually just lowered screen 6 inches to minimize vertical angle, but as low as I can go now with out the “sock puppets” getting unruly. I do have a power head rest adjustment on recliner to minimize fatigue issues from having to look up higher than human head designed.
I failed to originally mention for much of 16:9 content, I do watch in CIH format.
Without tight framing, agree vertical viewing angles for main content subject matter can be a bit much, headrest or no headrest.
Its certain content like some movies, Planet Earth, and IMAX that I built the single axis CIW masking system for. Am not trying to “fill up every square inch if I can”. Similar, but not the same. For immersion, horizontal viewing angle important, and since I'm not fully at min distance, vertical sizing of “Iron Man” still not too big an issue in my setup when I unmask and zoom out to fill horizontal field of view more. I do prefer ScopE.
I was not aware of “CIA” term. With all your excellent feedback, I now want to totally redesign the single way masking system I just finished to make it 3 or 4 way masking. Thanks! (I think?
) Your discussion also helped decision to stay on Arduino path for now since the JVC single 12V trigger (on topic!
) seems too limiting for controlling both anamorphic lens sled and external masking system. (JVC's internal masking is tempting for ease, but black velvet sure is nice)
I'll edit original post to say meant CIW masking, not fully at min distance, and recommendation to read all the informative discussion that follows.
RapalloAV, I also want to say thanks, I do remember some of the nice theaters with a good projectionist running them. I remember “my 1st time”, when initial prelim content was over, and the masking expanded out to ScopE, I thought “now we are in for something special!”.
Edits, grammer, and might have to clean my keyboard, the “E” seems to be sticking...
