Q: 9. Hi, does this film require any focus shift to account for IR instead of visible light?

A: IR film requires a focus adjustment - that is, after focusing using visible light, the focus ring is turned the distance between the white and red focus line/dot on the focus scale, because the focal point changes slightly in IR. That said, because the film is large format, it's a bit more difficult to gauge with bellows focusing.

Q: 10. I am loading the 120 size Rollei 400 infrared in a pinhole camera (6x6 size) but I don't see any frame numbers on the backing paper. Does it have any? If not, can you recommend how often to turn the film to the next frame?

A: Hey there brave soul of infrared endeavours! There are numbers on the film itself, pretty sure not on the backing. You will need to measure turns to get 6 centimeters. I would take strip of paper and measure 6cm on it and see how many turns will give you 6cm and a bit. Other than that, use complete darkness for loading/unloading too. Hope this helps :)
