Living dangerously. I bought ONE roll of Rollei IR400, probably not enough to figure out exposure.
To maximize my chance of success, I'm thinking over a few ideas.
2) I have a 'mystery' IR filter from eBay, described as 760 nm cutoff, best guess is close to an 87. I thought this would work with the IR400, but lately I hear it's now called 'near-IR'. I knew the filter would work with HIE, but now I'm not sure about the IR400. Is an 87 filter response outside the IR400's range? I saw a spectral plot that showed it reaching about 50% response between 750 and 800 nm, but maybe that's changed. Maybe I should just use a 25 red?
3) Winter in Michigan: Maybe waiting until there is more than one cloud visible in the sky?
4) Given the gamble in getting exposure figured out, is stand development a usable 'crutch' for ambiguous EI situations like this?
Thank you
