What Projector for 16ft wide screen?

Can anybody suggest a Digital projector for showing on a 16ft wide
screen in a school hall?
Showed  EXODUS there on the weekend and a friend lent me a Toshiba
Projector which supposedly
delivered 2000 ANSI lumens but the picture looked dim particularly the
night scenes.
The Dvd was  letterboxed but not anamorphic. Would an anamorphic DvD
have delivered a brighter picture?

Would a Panasonic PtAx 200 give a brighter picture?

Regards,
Peter Mason

Get a sensitive camera light meter, a Luna Pro will do.  Measure the ambient
lighting with the light turned off.  Tell me what numbers you get.  The
brighter the room is, the more light you need to pour onto the screen to get
acceptable shadows.  The 16 fl. rule does not apply if the room is not dark
enough.

Probably not.  You're at the point where you probably want to avoid the
cheap consumer projectors.

The hall was dark and there was no ambient light to speak of.

"Exodus" was beautifully photographed in Super Panavision 70 and MGM/UA
continues to sell a sh*tty letterboxed transfer rather than an
anamorphic transfer.  But to discuss screen brightness, NO, an
anamorphic would not deliver more brightness. Approximately the same
element area will be used because the letterboxed image is zoomed to
fill the same area as an anamorphic DVD.  The big difference is the
sh*tty image quality you get when you zoom the picture.  I've run
"Exodus" on my ten foot screen and after a while you get accustomed to
image quality, but a good anamorphic transfer would yield a much better
picture.

Brighter than what?  As I said, zooming a letterbox image gives you the
same projection area as anamorphic. (Same number of pixels with light
passing through them or bouncing off those itty-bitty mirrors.)

A TOSHIBA TDP S8.
Supposedly giving 2000 ANSI Lumens.

Maybe the lamp is starting wear out? We have some run of the mill
Epson  projectors at work that are used a lot & they fade out with
time.
