Near IR. Intrested?

[LionFlyer]

For the last couple of years, I have been fooling around (not making a living at photography makes that easy) with an old (for digital) Olympus 2020 2.1 Mp digital viewfinder camera. I got it after reading about how well it worked without modification simply by adding a Hoya 72 IR filter to it. A side note. I can also do IR work with my Sony S75 but a tripod is required where as the Olympus can be hand held. Here is one of my early pictures taken with the Olympus and a Hoya 72 filter. The flowers were dark purple to my eyes. I never saw the ant until I had the image on the computer screen. Recently I have been trying out the same filter on a Yashica Lynx 14e using Kodak HIE IR film. Seems to me that using a RF and opaque to visable light IR filters is a natural. I find that Kodak HIE is about 4 stops faster with the same filter than using the Olympus. Is any one else using IR film with their range finders? What do you think?

lf,
have you tried the konica near infrared film?
it's easier to use than true ir film and the results are kinda cool!

I looked into that film and I liked that one could (un)load the camera without a dark bag. My only IR filter is the Hoya 72 which as the name describes, has its pass band beginning at 720nm. I wish Kodak named their filters such. If I remember right, the Konica film tops out around 800nm where as the HIE is peaking about there with sensitivity out past 900nm. So I thought that my filter was a bit harsh for the Konica film. What is a good filter to use with the Konica product? I am thinking some where along the lines of a wratten 25. Is that enough to get the white leaf effect?
