Surely, someone has the true Reciprocity data for IR400! I have only found 1 chart out there and the values are too high to be believed
1m needs 9m
1m 40s needs 22 min
2 m needs 35 m
There really should be better info out there!
If you have any data please let us know
I want to do up to 10 m exposures along the ocean. Perhaps there is another better film for long exposures Ruth better Reciprocity values. Could any of you suggest a better film? I will be using
Ordinal.

Re: Rollie IR400 Reciprocity
It's something you will have to experiment with and bracket the exposures to find out.
I have never heard of the developer. Sorry if that's not much help.
