The NIM Giant Screen Laser Projector Experience- Part Two

June 23, 2017

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.

The NIM Giant Screen Laser Projector Experience – Part One

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

The sea change in cinematic theatrical projection is the relatively recent switch to digital  systems. Just as the way film systems evolved technically, digital is doing the same thing.  Film went from grainy black and white flickering silent cinema to sound on film and color and from almost square screens to widescreens that got larger and larger.  Digital has gone from 2K definition which allowed some pixels to be seen to 4K which solved that problem and from and from light bulb to laser lights.  The National Infantry Museum has one of the very few theaters in the Southeastern United States with state-of-the-art Giant Screen laser projectors.  The museum’s theater also has one of the largest screens in the Southeast.

70 mm IMAX film projectors took up a lot space in the large NIM IMAX Theater projection booth. I took this photo in 2010.

Up until last year, the NIM still used  IMAX 70 mm film  projectors. IMAX 70 mm was as good as it got in theatrical projection until digital laser came along. When IMAX switched to digital laser, the museum dropped IMAX and switched to Christie 6P laser projection, and changed the name of the theater to Giant Screen.

When I saw the new documentary “Aircraft Carrier,” I was so impressed with the experience I decided I wanted to learn more about the Christie laser projectors. I wondered why the huge picture on the screen seemed so much more vivid and immersive than the one produced by 70 mm film projectors.  I was able to take a look at the projectors and get an interview with Theater Technical Manager Brad Skipwirth.

I’ll take you inside the projection booth in my next post.
