>>3435830Is Kodak High-Speed Infrared or any other "true" bw infrared film still available?
The other ones I know of are panchromatic and sensitive only to 820nm.
I do have some Roller IR 400 sheet but have not got around using it cause for some reason its on annoyingly thin base. (When I tested it and developed it in paterson orbiter I ended in having all 4 sheets stuck together.)
