Kodak color film in 10" x 6 ft

erian · Jun 7, 2018

I discovered that at least until last century Kodak offered professional color film also in a roll uncut in width - 10" x 6 ft.

What may have been the reason behind such product?

I guess it was used for the Cirkut camera Model 10.
Otherwise a major market for films in long rolls in such widths was aerial surveying.

Aerial mapping. Topographic maps were all made from overlapping 9x9" contact prints, and if you used a stereo viewer you could look at the photos and see the landscape in relief. Typical air photos will overlap the next frame by about 50%, that makes the 3d viewing possible and thereby determine heights of land and contours.

For aerial surveying one did not use 6feet rolls.

Yeah, 6 ft seems kind of short, unless you were doing a small area. Here is a 200 ft roll of Aerochrome III for sale:

EDIT: this Zeiss brochure for an Ariel photography system makes for a fascinating read on an area of photography I never gave a second glance: Dead Link Removed

That broshure already is 22 years old, but basically shows the peak of film survyeing. Most of these cameras were succeeded by digital ones, also laser scanning was introduced. Surveying got more complex.
The same time all that opto-mechanical postprocessing vanished too.

I was mostly interested in the GPS oriented grid controller and all the support hardware. I'm sure the camera itself has long been replaced by digital, but it’s still interesting to know how all the support hardware works.

Very true! I misread the 6' length. Could be for a copy/process camera use I suppose.

I do not know of a process camera using spooled film. Only sheet film.

It's absolutely Cirkut film. That came in 10 inch by 6 foot rolls for the Cirkut 10. I have some in the freezer in both Portra 160NC and Portra 400.
