[photo-3d] Re:Curvzature and Kodak Ektalite

[Jacques Cornet <jacques.cornet@xxxxxxxxx>]

I read with interest the notes from Peter Homer, Mike Canters and others on 
the Ektalite screen.

I bought, and still have such a screen. I bought it from Kodak Brussels, at 
the same time that I bought my V.M 500 projector... in the 50ties or early 
sixties. That is to say long before projection  television (at least in 
Belgium)

I have lost the notice, but remember that thev screen is made of a special 
aluminized coating developed (as was stated) together by Kodak and 
Dupont.  As I remember, microscopic "cups" of aluminium in a plastic 
matter. The curvature is designed to give a very narrow vertical angle and 
a broader, horizontal one allowing projection in semi lighted rooms.  So it 
is made for slides projection and does not seem to distort the images.

It is perfectly suited for VM: just the right format and about two F.stops 
more light...
(I still have to check if it, like myself, did deteriorate with age...)
