Hey all,
I was perusing Freestyle today and saw they sell "cans" of film. Now, I understand this is for "rolling your own" film canisters for 35mm.
I thought about doing this. But, to those who have done it before:
Is it difficult to do, and do you really come out cheaper? A 100' can of film is $30...approx. how many rolls of 24 or 36 exp. film can you get from that?
I've been doing it for more than 30 years, so I have a little practice.
It's a bit more economical than purchasing loaded cassettes. A 100ft bulk roll can be cut down into about 18 roles of 35 exposures (which exactly fills an 8x10 in negative sleeve, 6-5 exposures strips).
I've always used a bulk loader - I purchased a "Telesar" model more than 30 years ago, and while the automatic counter mechanism gave up the ghost several years ago, the basic functionality remains - it provides a light-tight method of spooling the film. I can count the number of times that the handle goes around, and that's pretty close to the number of exposures. I have a couple of others that I have acquired along the way, but the Telesar still works just fine.
I have been reusing the same cassettes for most of the 30 year period. The source is irrelevant since it's no longer available. There is a theoretical concern that grit could become embedded in the felt light trap and scratch the film - I just wipe the felt with a hard edge, usually the back of the scissors blade, to dislodge any grit that might be there. I had one instance when the film was scratched, but that was when I was experimenting with a bulk loader that I bought at a garage sale for 50 cents, and the lesson was that you want to make sure that the design of the loader doesn't force the film to pass over a hard edge.
The one thing that you might have to do is be prepared to renumber the frames since you can't rely on factory numbering. I've used either a Koh-in-Noor Rapidograph with India ink, or a Staedler "Pigment Liner" for this - either puts a very dense line on film that is permanent. You do need to allow time for the markings to dry before you load the film into sleeves. I've also used Sharpies, but they aren't as dense, so the numbers aren't as distinct.
