The "Free Film" concept. I see.
But that of course makes only sense if one can convince the customer that only oneself can process that film.
The lawsuit near the end of their run was due to the fact that they switched to C-41 film and falsely claimed that only they could develop it.
...was a bit confused why the negatives were copies of the slides.
The polyester based film bases are harder on winding mechanisms - they don't stretch or tear like acetate will - and customers have an infuriating habit of trying to stretch a 36 exposure roll into 37 or 38 shots.@Mainecooonmaniac, why would a different film base be harder on a camera? No reason at all.
I understand that polyester films don't stretch or tear - which is why they are NOT used in movie cameras. Better the film break than bollix up a hugely complicated and expensive piece of equipment.The polyester based film bases are harder on winding mechanisms - they don't stretch or tear like acetate will - and customers have an infuriating habit of trying to stretch a 36 exposure roll into 37 or 38 shots.
37 or 38 exposurers on a 36 exposure roll is NOT streaching the film. There is enough film on the roll to easily get 37 exposurers or possibly 38 depending on the distance from the cassette to the take up spool of the camera. Mechanical cameras have 2 dots before 1 on the counter, the first dot might have foging but the second will not unless you have pulled a lot of film out for loading. Autoloading cameras use less leader allowing more exposurers per roll. The extra film is there to ensure the number of exposurers printed on the roll for those that wind extra film onto the takeup when loading. I had the film slip on my Yashica TL Electro once from not winding enough film onto the tkeup and I usually got 37 frames per 36 exposure roll. My F4 does it without trying.
Film for movie cameras have to be more robust. A movie camera can have hundreds of feet of film while 35mm film will only have 6' of film for a 36 exposure roll. Also, Movie film is exposed 24 frames per second while 35mm cameras don't expose film at those frame rates.@Mainecooonmaniac, why would a different film base be harder on a camera? No reason at all.
Still. Makes. No. Sense. Sir.Film for movie cameras have to be more robust. A movie camera can have hundreds of feet of film while 35mm film will only have 6' of film for a 36 exposure roll. Also, Movie film is exposed 24 frames per second while 35mm cameras don't expose film at those frame rates.
Was it a Mitchell? BTW, do regular 35mm still cameras have problems using movie film stock? Or they're more or less the same.I have seen a motion picture camera use a 1000 ft (~300m) roll of movie film in under one minute. I have seen a roll of estar based MP film jam under such conditions and the camera literally exploded with parts scattering over a wide area with great force.
It makes a difference!

Thanks for your input!I don't remember the camera type. It was an ultra high-speed model, and that's about all. MP and still film use different pitch perfs and different shapes. IDK what kind of problem this might cause for either camera, but I am quite certain that still -> MP is worse than MP -> still.
