I have a very simple procedure for shooting with IR filters that has served me well. First of all I do NOT make any adjustments in the ISO, I've never been comfortable with the thought of filters changing my ISO! All the filter does is affect how much exposure I need to give the film, plain and simple. So I meter the scene, and make up the desired filter factor by opening up apertures and/or lengthening the exposure. That's all. Takes about two seconds and there is zero math nor memorization.

I'm with Keith on this, always seemed the simplest way to do it, especially if using different filters as I do.

I also have a question.

I see that freestyle offers two Lee filters, one an 87 and one an 87C. They specify that the 87 lets in light above 740nm and the 87C lets in light above 775nm. Are these for different films? If so, which is for which films.

I think the 87C will be too high a cutoff for most of the films on the market. I use the 87 and it's already +10-14 stops, depending.

So, unless you plan to do digital IR or have HIE in the fridge, skip the 87C.

With the Rollei IR, would the 89B work?
