BIGGER film formats are the best way to go with 8 perf and 15 perf sizes!
Here is the Megadome theatre at the Science Museum where I also work.
As you can tell, the equipment here is very similar to that in the other booth, just bigger of course.
Here is a platter the film sits on. This is about 40min of film, and that's the usual length for the kind of films which are shown here: mostly documentaries and special films. You usually don't show any films any longer than this because as you can see this film is quite large and very heavy as it is!
Here's what the film looks like when it arrives in the box. These reels arrived "tails out" or with the end of each reel on the outer edge of the film.
So, here I'm rewinding the reel back to the "head."
I then run each reel off onto the platter...
...and splice each reel together with this special splicer which doesn't use tape, but "welds" the film together instead, making a super strong splice!
And that is how you build a 70mm film!
But now, everything gets even BIGGER with OMNIMAX!
Back on May 16th, 2001, I went to the Discovery Place museum in Charlotte, NC. There, they feature OMNIMAX. Here are some shots I took of their booth. The public is allowed to see this through a glass wall.
This IMAX film is also known as 15/70, meaning each frame is 70mm wide by 15 perfs (or sprocket holes) on each side.
