Today I bought some negative storage pages (you know, the 8.5 x 11
inch plastic binder pages). The brand was Print File. On reading
the advertisement on the back, I discovered they are selling
pages for storing 70mm. At first I thought this was the metric size
for 120. (The picture size was the same 2.25 in. square).
Then I noticed they said square or rectangular. Then I noticed
they held a different number per page and seemed to be sized differently
from the 120 pages they also sell.
The question:
Is this stuff just for the Hollywood movie types to store selected
frames from their 70mm movie films, or is somebody making 70mm
still cameras to shoot the 70mm movie film? If so, is the film
packaged in a nice metal cassette like 35mm? If so, will this be
the future film for medium format cameras? Or is all of this
just marketing hype for some mundane size with another name?
If it *is* 70mm stills, this could be the start of something big. :-)

You can buy a 70mm back for the Hasselblad and other 2-1/4 by 2 1/4 inch format cameras, i.e. one's that take 120 roll film. These are bulk film backs which can hold up to 500 frames, if memory serves me right. In any event, a lot more than 12 or 24 frames on a roll. The basic difference is that they have sprocket holes like 35mm film in order to smoothly transport that much film through the camera.

I don't know of any other specific applications (beyond the obvious motion picture industry), but 70 mm film is used in some x-ray cinematography apparatus for angiocardiography (visualizing the functioning heart and blood vessels). While this apparatus uses 70 mm roll film, the frame rate is generally slower than that used for standard cinematography (i.e., < 24 fps). In this application, individual frames are kept, as opposed to viewing a running film. === Larry Lippman @ Recognition Research Corp., Clarence, New York === === UUCP {decvax,dual,rocksanne,rocksvax,watmath}!sunybcs!kitty!larry === === VOICE 716/741-9185 {rice,shell}!baylor!/ === === FAX 716/741-9635 {AT&T 3510D} syr!buf!/ === === TELEX 69-71461 ansbak: ELGECOMCLR {via WUI} ihnp4!/ === === === === "Have you hugged your cat today?" ===
