There is very little which hasn't been patented, although certain
optical companies don't patent their designs, prefering the trade
secret method of design protection, plus the very high cost of entry
into what is actually a very small market with little upside potential.
In the instant case, the "rolling loop" method is well protected.

I had a question that I can't get google to answer on IMAX - perhaps someone
here could help me:
Is there a B&W stock available for IMAX?
Also, who makes the regular colour stocks for them?
I also love that the dimensions of the IMAX frame are almost exactly the
same as Billy Bitzer was using in the Biograph camera back around 1910!

Thanks for any assistance offered!
John.

Virtually anyone who manufactures film can make film for the IMAX camera
(color, black and white, infrared, orthochromatic, reversal). There is
nothing special about the film for an IMAX camera per se. It is the same
emulsion (-s) used in 35mm photography that's been slit wider and perforated
for the 65mm gauge. Also, not every IMAX release is shot 15perf. A bunch
of stuff now is computer enhanced from 35mm. There has also been some 8
perf. origination as well.
Get your butt to the public (or private library) and read some past issues
of American Cinematographer. If you go to Imax.com and print out the list
of Imax films you can then cross reference those titles with the titles that
have been written up in AC. Back in the day, I didn't spend every weekend
trying to get laid or stoned. I spent a lot of time in the microfilm room
of the library reading old articles on film technology. And I was found
wondering the stacks trying to find books of any vintage on the subject.
Good times and made me a better student. If this is your passion then
embrace it and do the leg work. Don't let Google do all the heavy lifting.

Sure. Remember, it's just 70mm with type I perfs. Kodak still has a few
70mm aerial film stocks that would run fine through an Imax camera as
well as a Hulcher.
Which is surprising since Kodak is dumping films from the catalogue right
and left. The graphics division used to have a foot-thick book, and now
it's down to three or four films.
Quote: Also, who makes the regular colour stocks for them?
Kodak and Fuji both make stock that will run in the Imax cameras. And
I think they are pretty much it for color film at all these days.
Ferrania makes some color print films. Orwo and Svema are out of the
color business. Konica-Minolta (nee Sakura) are out of color business.
Agfa is out of business. So Kodak and Fuji are all that is left for
anyone.
The thing about 70mm Type I is that you can make it on the same cutters
and perforators that make 35mm.

What is type I perfs? Is that what they call 70mm with 65mm KS perfs?

How would you run 70mm film through a 65mm camera? |

No, type I perfs are at the edge of the film. Type II is the 65mm KS perf
on 70mm film.

No, Imax is 70mm, really. It's not 70/8 which is really 65mm. Remember,
Imax uses double-system sound so there's no need to waste space on the film
with a soundtrack.

The print is. The camera shoots 65mm.

There may be no need to but they do. Maybe they put timecode there; I
haven't seen that variant. But IMAX is definitely 70mm-with-65mm perfs.
I've not handled any IMAX 65mm negative but it would be rather foolish to
use a 70mm negative as you would not be able to contact print to 70(65)
print stock. Obviously you've never seen what an IMAX print looks like so
check this out:
http://i4.photobucket.com/albums/y129/filmteknik/misc/imax1.jpg
(taped to the LCD monitor hence the interference patterns)
And if you rummage around the IMAX Corp. website you will find references
to IMAX 65mm cameras. |

Oops, you're right, they are Type II perfs! I am thinking of Astrovision
with the Type I.

I never really think in terms of Type this or that EXCEPT I have seen a
70mm camera with some sort of wider perfs that was used for filming rocket
launches and I thought that was Type I or something like that. The camera
I examined had a beater type movement. |

I've seen big rocket launches filmed in 3-D IMAX. Very impressive, but,
well, I wish they had used a vertical, not horizontal, format.
