I am taking a trip round the world, and I had the chance to buy some Kodak HIE infrared in Berlin. I'd like to shoot it, then mail the film home before I have to face an airport/scanner.
I do have a red # 25 and a red #29 filter with me, so I think I am set in that regard. But since I've never really done B & W infrared, I have no idea how to rate the film. I have seen postings at various websites suggesting 100, and 200, and 400.
Assuming I am shooting at mid-day in bright sunlight, what are your suggestions? [Will your answer change depending on which filter I use? Or, will the infrared information come in at the same rate, regardless of which filter I pick?]
Hope this question is not too basic. But I could not find anything here via the Search function.
