Aye, Malcolm....
The One Minute Man had a momentary Brain Fart!
You are right.

And about movie film.... are all the movie stocks cursed with the remjet
coating like the old Kodak 5247 (memory may fail me here too, on the exact
designation!), and can you get relatively short lengths? say 100 ft instead
of 500 or  1000ft?

If not, they might be a viable alternative.... With the advent of blue flash
bulb, then later,  cheap electronic flashes, I seem to think that that the
demand for amatuer tungsten film simply faded!
I have printed the old Seattle Film Works Film, which was the Kodak Movie
stock, and other than a narrow range of lattitude, it produced good color-
required accurate metering since if  it was over or under exposed, the color
slopes went whacko-gaga!
BTW, I did a roll of the new Seattle Film and the emulsion has the code bars
exactly like Polaroid One film- so whoever is making Polaroid is now making
Seattle Film Works.
