The IR400 is from macodirect, and when I say "I have" what I really mean is "it's in the post and I expect to take delivery this week". I got it because IR820 is discontinued and no longer available at a reasonable price and while I have most of a decade's worth in 4x5, I only had 9 rolls left in 120 and it's my favourite landscape film. IR400 isn't as nice IMHO, but it will have to do.

While I'd love a proper long-roll 70mm spiral, it seems either the prices are silly (Jobo, especially the 15-foot 3xxx version) or they're near-impossible to use. The 220-spiral approach works well for me for now as long as I have a reliable way of marking 20-frame boundaries and therefore not wasting a bunch of film on cassette changes. Loading the 220 spirals (for Jobo 2xxx tanks) is no problem.

I've just started feeding the 2405 into my scanner now.
I wast aware there was a JOBO that took 15ft of 70mm hmm is that a processor style or hand developer tank?

Also I would think the 70mm would have more issues with IR light leak than normal film... But I could be wrong.

I would also suspect the prying open of the cassette would cause light leak issues and defeat the purpose of the felt when you want to change a roll out of the back in daylight.

I haven't had any issues now that I've labeled the direction and stuck to that. But I started with never used cassettes so I started ahead of the game.

I get frustrated with 70mm, I've considered selling the lot... And moving on, and then of course I just bought a graflock 70mm back for a 4x5 so now I'm all in... :shrug:
