Does Two 120 = 220?

I have different tanks... so i don't really need to answer this... but can I load two 120 back to back on one spindle or should I just run two, three or more tanks at once?

My logic is if a spindle can hold a 220 film, it should be ale to hold two 120s... or am I missing something?

Would there be changes to developing times?

You are working in the dark, what if you end up overlapping the film on top of one another? The lapped portion will not get developed properly if at all. The film leader that ends up on the take-up spool, you are going to have two of them from the two 120 rolls versus just one from the single 220 roll. I don't think it's worth the risk, even if possible.

Thanks,

Although - if you use the tape at the end of the first roll to attach the start of the second, maybe it will work?

+ 1 on excanonfd It sounds logical in theory - but in real life ? hmmm. . . i just started doing medium format after about a 10 year hiatus and before i did my first roll i invested in and ruined a roll of 120 in order to practice loading it in daylight several times, just to make sure i had the technique down - if you are really curious/serious about loading 2 120 rolls onto a 220 reel - if you want, try it in daylight with 2 practice spools, i'd be surprised if you still think it's a good idea - but who knows ?

I think I'd agree that it's too fussy to be worthwhile: I'd just run one or two rolls at a time, depending how big your tanks are: in trying to get two rolls on one reel, I'd think there might be more risk of putting a kink in the film or some such.

These days I usually shoot really slowly with 120, so I wouldn't personally be in a rush to put more of it in one basket than I have to, anyway. I've got a tank that can do two at once, and that's probably pretty sufficient.

(I also suspect that two 120 rolls are longer than one roll of 220, anyway: each roll will have some leader leeway and all: I think if you did want to try it your best bet would be to use a reel that loads from the inside-out so you could tape one to the other. A Paterson type would probably hang up on the joint or any misalignment.)

What I did was use the tape that's on the end of the first roll (the one that tapes that roll to the spool),and stick the beginning of the second roll to it Works fine, though you have to align carefully edge to the edge...

This seems like way to much effort to save way to little, with a good deal of risk. One of my favorite aspects of processing 120 film is how easily it loads on a spiral roll.

I am surprised at how easy it did go on... I had fears of causing crescents...

I just tried this. 120+120+tape=220. It's pretty easy besides. Although I can see where it would be nightmarish with a bad reel...

did you shoot it as 220? Or just load 2 120 in the tank?
