The NIM Giant Screen Laser Projector Experience- Part Two

A Look at the National Infantry Museum’s State-of-the-art Giant  Screen Laser Projectors – Part Two

70mm IMAX film is fed from a revolving platter to the IMAX projector.

Not only was the 70 mm IMAX picture on the huge screen, one of the largest in the Southeastern United States, an impressively immersive experience, the projection booth was also big and elaborate.  The two IMAX 70 mm film projectors filled the largest projection booth I have ever seen.  Now, the theater is showing a huge picture on the Giant Screen that is, in my view, just as good, or in some ways even better, with projectors that that don’t come near filling up the booth.

Giant Screen Christie Laser projectors use hard drives, DVDs, live digital presentations, anything on a computer instead of film.

 

Theater Technical Manager Brad Skipwith said that instead of spending a lot of time loading the 70 mm film, the operator just inserts a hard drive and pushes a button.  He said, “The picture quality is a lot better. It’s way more sharper than film. It’s a lot more crisp.” When I pointed out that film resolution is still higher than 4K digital, he said the reason laser projection is clearer because laser light is brighter, especially when running 3D movies, and that “When the film runs over and over, you, of course, start seeing lines, you get dust. You get none of that with lasers.”

Another plus, he said, on the laser side is that 4K Xenon lamps last about a thousand hours, whereas laser lights will last ten years or more.  That’s one reason that the National Infantry Foundation decided the laser system would provide longer life and lower cost of ownership. Also, going totally digital saves thousands of dollars in shipping charges.  Film and film canisters are quite heavy. Hard drives and DVDs are not.

Now, all the theater needs is YOU.  The last two times I went, the theater was almost empty. That’s hard to understand because the documentaries that are being shown on a regular basis are really worth seeing in my view. Fortunately, the free movies shown in the summer for the kids draw good crowds. The museum comes out ahead on them because the concession stand does well.  Movies and popcorn go together.
