Hi Cineramax,


I read one of your old posts about being a former auditor. Well, it audit season now. I guess you don't miss working until midnight every night.

Have you seen a setup with 9" CRT w/ special lenses for curved screens and the Torus? If so, how does this compare to Chris Stephens' modified 9500LC and Teranex setup in terms of illusion of 3D depth?

Could you also tell us a bit more about the special lenses for curved screens? For the Barco 909, they have a special lens available as an option for curved screens. Is that made by Corning (U.S.) Precision Lenses? Is it liquid coupled? What is the optical resolution? Is it 12 lp/mm at 50% MTF like the standard HD-120 on the Barco 909?

Thanks

Not after the Enron thingy.

It was a great business school and perhaps it's most valuable lesson to me was in a capacity to present, negotiate, and influence at the highest levels.

I cannot give you the details to your question, for competitive reasons.

All i can say is that if you call a lens company and tell them that your HD-10R does not focuss on your curved screen of so and so width, and such radius. They will get back to you.

Subjectively it looks 12 l per mm.

Chris stevens double stack is not a good idea. The TORUS is sorely missing. Is like dressing in a Tux barefoot.

The REVOX projection system that I may design would be a Criss stevens upgraded 9500, bought without lenses.

The curved screen lenses designed for barco would then be added.

A sanctioned TORUS screen would complement.

I am about to ask Don to make a couple of Torus skins in 2.9 XENON WHITE. If anyone is interested in this production run contact alan.


after seeing Indiana Jones on HD 2.35 is becoming a more attractive format.

I believe that going with a 2.35 aspect ratio that has a 16 x9 image within (FIXED HEIGHT / var width) is maybe the way to go.

I will post on the processor forum.

How would the Xenon 2.9 compare to the Silver 3.2 ?

Peter what is this xenon white 2.9 gain. I jave never heard of this before.
Sounds interesting!
With this high a gain it would only make sense to use this with a curved frame.

CINEMAX, your experiences with the Silver 4.0 gain would be really appreciated as I noticed on your webpage that you have had experience with it.

Also, I was under the impression that the screen only looked "silver" when there was no light projected onto it, and that during projection, it the whites would look very white. Is this incorrect ?

Mine is DONE! Call Me! Details with pics soon.
Don't leave us hanging here like this. We NEED to see those pictures RIGHT NOW. Honestly :D

Heck i haven't moved an inch since you mentioned that you will post pictures the first time in this thread. This was several weeks ago. I need to sleep! :p

Hehe.

A special batch that is supervised by Don Stewart himself.

It is sprayed and sprayed until it achieves that gain.

This is the WAY to go for me SILVER has the same effect on whites as a grey screen. It makes a protest march look like return of the living zombies.

Thanks for that CINEMAX, good to know before stretching to the $25sq/ft. Any more details on the 2.9 gain white screen ? I'm guessing the view angle will be similar to the silver screen ?

Snaggs, I ordered 2 sheets of 5' by 10' yesterday. Just look in the thread for the phone number. Ask for the screen material. They know exactly what you want.

I can hardly wait for it to get here :p

Oops... I see the screen topic changed again. Nevermind, Snaggs.

Xenon white??? And just when I thought I was all set.

Welcome to the darkside.....

I turned 50 this week, and between the party stuff, old age, and learning how to converge a 9500LC and operate a HTPC I've been busy...besides, it's my wifes camera, I need her to put the pics in. I only know how to type.

It looks great, but needs tweaking. (actually, its the PJ and PC that need tweaking, I have a couple things I'm asking Don Stewart about re: the screen material, but all in all I'm very glad I did it and would love to share pics (if I can ever figure out how.

This week, I promise!

Thanks,

Jeff
