70mm loading/developping
70mm loading/developping
I would love to see 220 B&W but 70mm is a far easier solution. The 2013 ULF Ilford progam had 70mm double perf on the list but I'm not sure how much was ordered or produced. I will get a 70mm double perf order in for next years run.
In the 70's I would load my Hasselblad 70mm back with 25 frames of 6x6 and process it on a modified 35mm 36 exp reel. A poor man's 220 A24 back!
there is a solution to avoid the need of 2517 spool(70mm in 220 lenght, 172cm?): using three parts of 2500 jobo-reels.
5m or more depending thickness needs a special jobo 70/5m drums and loader. one kodak CN film vericolor HC can be spooled with 6.5m in 70mm cartridge. Linhofs reel has a slot.
Ilford should offer longroll 120 with a roll of backpaper for start and end.
if no other choice(e.g. cutting down 70mm) fuse two 120 and remove paper inbetween.
i will add 0.1mm transparent tape to kiev60 to get better flatness.
--------------------------------------
Just got two 70mm cutters from xkaes at aol.com. one is cutting centered(2 blades) leaving some perforation remains which could damage machines, second one is cutting only on one side(1 blade) leaving perforation on one side untouched.
have all kinds of 70mm backs. HB, Mamiya, Graflex. in HBs i have three, one is defective(sealing) i will take the holder and cut down the dents of image-counter-wheel to load unperforated 70mm film. centered cutting will be no problem anymore for labs.
Have special very thin agfa film for aerials to use with filters. no IR effect. avipan 200S if i dont err. have documentation. handling is a mess but should be no problem with patiences. i liked hp-combina which is loaded from center, film tongue being fixed there. could probably develop thin 220 there. for jobos or others
only reels must be dry...
