[BadVista Advocate] projectors for an ad campaign

[Don Hensley]

The only thing about that is I don't know just how much light a digital 
projector can pump out.

Think about it, the equation here is like illuminating a building wall with a 
flash light, or a flood light. They will both do it but the effective light 
from the flash light will most likely not be observable to the human eye, if 
spread over much area and distance.

I'm not familiar enough with the digital projectors to be able to say much, 
except that I know the ones I have seen (like at presentations, etc.) would 
never work... more like the flashlight, if you see what I mean. But as I said 
for all I know they make the digital versions in major big high lumen output 
versions.

I know I would be skeptical of a old style movie projector making a very 
brilliant display if used on a really large building... it too would be more 
on the flashlight end (just a lot brighter then any digital unit I know 
about) But as I said, my knowledge of digital units is very small.

And do they make digital projectors for movies? I thought that was mostly, if 
not all, more like a slide projector, or over head projector.

We don't need a dedicated one for this. How about we borrow one from a
university, camera club, store, friend, etc? We could probably even
rent one. I'm not talking about a old school film one, I'm talking
about a nice digital projector that they use for like powerpoints or
cheap movies.
