Trying everything that may or may not spit out IR today now that my D70 has an IR filter on its sensor. And per the direction that Bjorn set me on, I bought myself an Elinchrom strobe. Voila! :biggrin: And at less than a third of the strobe's maximum output @f10, too. This is a bare flash tube. I guess I need an IR translucent softbox now.
