I jotted down some notes from this forum when I was researching all the new IR films and possible filters to use.

With Rollei IR 400 and the 092/ RG695/ 89B filters, I have a suggested EI of 12-15. My own method is to enter this ISO into my handheld meter and work from there.

For a dev time I've written Rollei IR 400 - 12 mins 20 degress Rodinal 1+50. I'll be trying this as soon as my filter arrives.
