I volunteered to do a presentation for a local community function on poverty which ran last night in a local auditorium. I took a picture of the screen it ran on. I thought you might enjoy this.

I used my home theater projector to project the image. The pj was a Sanyo xu-30. The projection distance was about 50 feet and the image was running 4:3 from a svideo connection off a dvd player. The video source was a VCD from a presentation created from Ulead's DVD picture show where you can create a presentation burnable on a regular CD-R which can be playable on a regular DVD player.

Anyway, the screen size was 20 feet across. And with alot of ambient lighting, the pix was not too bad.


Huge Screen

Ok, thanks, I've sent a delete request and will repost this when my site is fixed. Not sure what's up with it.

Yes. The pic is coming from a different site now. Looks great! Too bad you couldn't get rid of the ambient light. It looks like the screen would have given off enough ambient light by itself. (The audience lights were kept up for some reason - I supposed for safety in moving about.)

Nice looking stage too. Curved apron.

Nice.

The biggest image I've personally seen was from an AmPro AE-4/7400 light
valve projector that I owned for a time. (Prize from AmPro's bankruptcy
auction, which I went to.) With 5000 lumens to spare and a full assortment
of lenses of varying throws, I was enjoying watching movies on the side of
the garage wall on my neighbor's house across the street. That wall is
about thirty feet long and I had to use the longest throw lens (7:1) I had to
keep the image within the confines of that wall. (But even then, only 2.35:1
ratio movies would really fit properly. Anything else would display partly on
the grass and partly on the roof.)

Brightness was very adequate at that size, too!

If I'd had a larger surface to throw the image on, I'd say that it could have
managed a very watchable image at fifty feet wide, in a well light controlled
room or on a dark night outside.

Really big is really fun, no matter how you get it!
