Jason,

First of all congratulations on the boy to come.

Because I do not know your budget I assume you want to just start safe with
the minimum pieces, and be in a position to enhance later, not to replace.

I was talking to Richard about how to respond to your inquiry, it has many
angles on the analysis of what would be best for you, but you should read
the articles of 2.35:1 CinemaScope if you have not done so already. Richard
was drafting another piece on that subject but for rather doing 2.35:1
viewing using the zoom features of the projector, not with anamorphic
lens/transport, provided your projector has remote control zoom and remote
focus capabilities.

There are pros and cons on both styles of operation (with anamorphic lenses,
or without lenses using just the zoom), and this email is not going to
address those, but I would say that provided all the products are of
excellent quality, implementing one approach or the other has some
differences such as light output, utilizing part or all of the resolution
pixels on the projector chip, automatism, perfect pixel mapping all the way
to the farthest corner on the screen, the feeling (or actual) optical
compromise when adding more lenses to the light path, to mention a few.

So "better" is on the eyes (and the pocket) of the beholder, to answer your
question.

This subject is quite complicated and it should never be presented if not in
a complete form, because the options and alternatives could be
misinterpreted on their features, relative quality, ROI, etc. Reason by
which my series contained several parts, and other parts hopefully will come
to cover in detail the lens transports, lens, viewing experience, etc.

I should be able to write them one day, but the published parts should be
enough to familiarize yourself with the anamorphic system supported by only
a couple of projectors in 2006 when I started with this, and is now widely
supported by most projector manufacturers that have done partnerships with
the few lens providers out there, Panamorph is being the preferred lens
system by most projector partnerships.

I recommend for you to think in what Aspect Ratio (AR) you watch most, 16:9
or 2.35:1, and design your screen accordingly, considering that if you
mostly watch 2.35:1 and you choose a 2.35:1 screen shape, the moment you
project a 16:9 image it would be smaller in overall size, because the system
maintains the same height for both types of images. The result would be
that 2.35 images will impact you, but a HDTV 16:9 image using part of that
screen with black pillars might disappoint you after viewing a 2.35:1 movie,
unless you sit closer to the screen on those.

The opposite might be true as well, which is, that you might decide for a
16:9 screen where the 16:9 images would be great in overall size, but when
you project a 2.35:1 image the objects become proportionally smaller for
that AR, surrounded by top/bottom black (or dark gray in many cases)
letterboxing bars, no visual impact, not the one you expect from a wider
CinemaScope image.

The beauty of a CinemaScope system is that the screen itself is 2.35:1 for
images of that aspect ratio (or 2.40:1), the black bars disappear either by
zooming them out with the projector itself, or by letting the anamorphic
lens system and scaler stretch the image to fill the screen in the four
directions. The final result using either approach on a 2.35:1 screen and
image is that objects would have the correct relative geometric proportion
to the AR, it is not that heads and feet would be larger and will be cut,
but in some cases foreign movies that use the subtitling over the black bar
of the bottom disappear as well, on those there is nothing you can do.

Either approach (zoom or anamorphic lens) would give you about the same
feeling of dimension of those objects within the director's camera take, on
a very immersive and impacting wide image that fills your lateral viewing
angle to the max the screen can give, even wider than THX requirements based
on 16:9. In other words, the feeling of Cinerama 40-50 years ago when the
automatic system opens the lens and the curtains mechanically move wider and
wider.

So assuming you will buy a 2.35:1 screen and a 1080p projector with
sufficient lumens, to anticipate a drop of maybe about 30% of light output
after ISF from the out-of-the-box spec, you can safely buy both pieces now,
to start with the more manually oriented zoom approach and a rock bottom
investment, and if you like it and if you want to further invest on a full
automatic system that uses all the pixels and light output of the projector
chip, you might want to spend the extra $6K+ for the anamorphic lens and
transport, and possibly some labor if you rather have a professional
installation, and find one installer that knows this stuff.

I suggest that you make your design assuming you will go that way so the
projector and screen you choose, considering installation distances for
anamorphic lens/projector lens/ screen to lens ratio, would eventually meet
the requirements of the additional lens, plates, transport, etc. when you
install them, and the projector and scaler must be capable to do the
vertical stretch electronically (while the lens to do the horizontal stretch
optically), etc. So it will only be a matter of paying and installing
remaining pieces that you already know will work with your system.

Regarding your room light conditions, it is always good to have blinds that
cut the light that comes into the room, you can always get a screen designed
for light reflections, you should buy a projector that has sufficient lumens
to still project a decent image in a shaded room (with the matched screen
for that purpose), or run the projector lamp in bright mode (although that
increases cooling fan speed and noise), or set the iris to a manual position
that would show a brighter image during the day, or can even use ISF
day/night to store those settings after calibration.

It also depends if you are looking to imitate as close as possible the low
lumens of a local theater for film, or you want a striking image of the same
movie of the theater, but bright as HD Net, on a very large screen playing
Blu-ray sourced from film, even when is not the way the director intended
that film/lumens relationship. I am always looking for high light output to
open the possibilities, which will also run out as the lamp ages by the way,
but one can always compensate with wider settings on the iris, or running in
bright mode if the projector is installed away from your hearing level.

I would get a bright model with flexible lens shift in the four directions,
and motorized everything if possible. There are models that only have
manual zooms and focus, those would force you to buy the anamorphic system
from day one, because they would be very inconvenient for the manual
adjustments every time you decide to view another AR, imagine bringing the
ladder from the garage and playing with the zoom ring while your guests tell
you when to stop. There are also lens systems that you leave always in
place, but although anamorphic lenses are now doing an great job at
implementing the 2.35 feature optically, I would never want an additional
lens I do not need all the time (for a 16:9 image for example) in front of
the good quality lens of the projector.

I hope this is good enough for starters, it sounds like that new boy could
not arrive on a better place considering those large cartoons on Saturday
morning, for which you should start saving for replacement lamps (like the
College fund).


Best Regard,

Rodolfo La Maestra

----- HDTV Magazine Tips List -----

For the 2:35:1 amateurs like me - I'm considering replacing my TV with a
front projector some time this year. If I get a 16x9 screen, I'm
assuming I still watch 2.35:1 content, but with bars on the top. How
much "better" does it look when using the panamorph lens than without?

Also, some basic front projector questions:
The room that I would put it in has a lot of daytime light that is not
easily controlled.
I work from home and we are having a boy in September. I expect to watch
TV, movies, etc throughout the day as much as at night. Are modern
projectors still as sensitive to light as they traditionally have been?

To add on the Zoom 2.35 approach...

I hope to get that article out soon and it awaits me resolving some
technical measurements that requires a new lamp and at $400 per pop I
wanna get all my hours first. Good news is it is near the end of it's
life. :)

First and foremost the zoom approach with 1080p is 100% performance
valid. That article explains the nuances in that conclusion along with
how it could be argued to have a performance edge. But...

That small edge won't mean a hill of beans to most folks so the real
question is do you want variable fixed screen height for all aspect
ratios - zoom, or, fixed 1.78 and 2.35 aspects where a scaler forces a
fit for those aspects that are different - anamorphic.

Do you want an automated 2.35 adjustment - anamorphic, or a more complex
manual 2.35 adjustment - zoom.

Can you find a projector with the performance features you want at your
price? For zoom the list is:

<strong>Zoom 2.35 Pros and Cons</strong>
<ul><li>You need a projector, 1080p preferred, that meets the minimum
requirements which many will. Minimum 1.3x zoom along with lens shift or
vertical centering</li><li>A manual iris adjustment is the best route
for light output compensation</li><li> You will need a dark border above
and below the screen or you may be able to make out the black bars of
2.35 from the 1.78 source that are now over scanning your 2.35 screen in
this mode</li><li>No additional lens optical errors or mounting
concerns</li><li>With a 1080p projector you maintain 1:1 pixel mapping
of 1080p sources for a straight shot to your display eliminating any
artifacts induced by scaling</li><li>Provides an infinite range from
1.33 to 2.35 supporting OAR for nearly all content</li><li>No cropping
of the image or geometric distortion yet as with all OAR systems your
screen may not be filled out either, black side bars</li><li>A 2.35
source setup for your 2.35 screen will have on screen graphics from your
system that appear in the black bars above and below appearing above and
below your 2.35 screen instead and this can include sub-titles. Unlike
the anamorphic approach you will be able to see subtitles appear below
your screen for better or worse.

While I may be a zoom OAR fan, fact of the matter is I love my BenQ (it
has a 1.15 zoom) and I have a had a tough time finding all of those
features in a larger zoom range that fits my budget. I have contemplated
the optional anamorphic lens a few times over the last year but at $3000
plus I guess I am waiting on the right DLP projector to come to market
instead.

Bottom line is the beauty of the zoom approach is cost - you get the
2.35 bang for your buck and if done right a performance response to
boot. On top of that if you decide the zoom approach is a hassle all you
need do is add the anamorphic lens.

Yes, they have not figured out how to change physics although the
marketing departments and bell and whistle engineers try make us believe
otherwise with DAY/NIGHT settings. I don't think this is the best
display choice for your application.

First is your rooom lighting. For simplicity I use bright, medium and
dark terms. Some displays can do medium to the other but only a handful
can do bright and dark such as a Runco with two lamps, one for day and
the other for night, likely more than you wanted to spend. Another issue
is the lamp and the limited lifespan of them in heavy useage
applications - lamps are expensive but if you don't mind that then what
the hey! BTW, new this year is a long lifespan lamp exclusive to
Panasonic - don't have the details...

If you keep the screen small, 80-90 inches you stand a better chance of
overcoming problems. Both lamp power and manual iris help greatly to
getting the different output levels you would need. Still, this means
medium light to bright or dark and for you that means some bias lighting
at night to prevent a dark room or some shading during the day making
your bright room a medium room allowing a dark room app at night.

There are screens for this application that suppress ambient light.
Performance comes with question marks.

In the end it all depends on what kind of end result you want and if
this was confusing, well, it is. I recommend some professional help for
this kind of application.

Sure you don't wanna go with LCD or plasma for this app and save the big
screen for the right room?

Some more on day/night and performance

Plasma has nothing for this.

LCD with backlighting can do medium/dark

Can't think of any display that can handle bright.

A DLP RP would be a great work horse for this app since they use lower
wattage lamps that last longer and you can get those up to 73". That
said, it like plasma offers nothing for medium/bright, medium/dark.

All Digital Displays
While some may provide Day and Night settings remember that the
brightness and contrast controls are set for optimal dynamic range not
the viewing environment. Bias lighting is used to match the viewing
environment to the display light output. If you change the brightness
and contrast settings you will either clip the video or induce
scaling/processing artifacts into the image.

Thanks to both Richard and Rodolfo for the detailed info (and the well
wishes!).

I was sort of dipping my toe into the 2.35 water and have found it's a
bit much for me to consider the hardware for an anamorphic lens setup. I
also see that very few movies are actually in 2.35:1, so I may consider
the zoom option if I go with a projector. However, the windows in the
vaulted ceiling family room are high and not curtained, and I probably
don't need another project to cover them all.

I may just put an LCD (plasma feels a little "corporate" at this point)
in the living room downstairs and enjoy the rest of my CRT RP's life in
1080i...

thanks again!

Jason

Jason,

2.35:1 and 2.40:1 movies are no exactly a few as you said, in fact the
format is being preferred by the majority of new movies.

Over a year ago someone on the commentary of the Cinemascope article made
the same comment and I provided the statistic at that time (now is much
more) on the same commentary.

http://www.hdtvmagazine.com/forum/viewtopic.php?t=7161


There are companies that have motorized vaulted ceiling curtains if you ever
desire to go back to your original project, but as you might imagine they
are not for a low price.

For you very lighted room as the one you describe a plasma for day viewing
would be a problem if the light would reflect directly to the screen, a LCD
would be more appropriate, but when considering the price of a large LCD
size you might be on the price range of the projection/screen idea.

Best Regards,

Rodolfo La Maestra

----- HDTV Magazine Tips List -----

Thanks to both Richard and Rodolfo for the detailed info (and the well
wishes!).

I was sort of dipping my toe into the 2.35 water and have found it's a
bit much for me to consider the hardware for an anamorphic lens setup. I
also see that very few movies are actually in 2.35:1, so I may consider
the zoom option if I go with a projector. However, the windows in the
vaulted ceiling family room are high and not curtained, and I probably
don't need another project to cover them all.

I may just put an LCD (plasma feels a little "corporate" at this point)
in the living room downstairs and enjoy the rest of my CRT RP's life in
1080i...

thanks again!

Jason
