Steep projection angle

[rolfwenzel]

Peter,

you're pushing physics a bit too much.
Regarding brightness there will be a significaqnt difference between top and bottom, but the bigger problem will be your lens focus.
It is impossible within that distance to get an equal focus on your screen.
Whatever you will do I would expect minimally 60% of your screen will be out of focus, which is not that good for video content. :-)

Rolf,

Which minimal distance do you suggest? I can go higher.

Will it help if i also use 2 projectors and create a greater distance? Teh jpeg is still with the 640 but you can discard that.

I would see if you can get a test setup together - with projector(s) and screen.

It may work on paper but not look good in reality.

I think this is impossible to say what will or won't work without actually trying it.

Nev.
